    In search of 454SS seats. help!!

    I will build upon my last post; I will not say that I know with clarity if 1990 style buckets were used in 1991, but default to my buddy's knowledge citing that the 1990 454SS seats were specific... Maybe someone here has a 1991 full model brochure? I recently bought both versions of the 1992...

    In search of 454SS seats. help!!

    this discussion has stuck with me; I have always loved the 454SS trucks, and had thought I new a fair amount about them… but I am guessing some of that knowledge has faded with the mists of time; I reached out to a buddy who has one, and what he told me might give the OP a sigh of relief; He...

    Gen IV BBC bolt in compatibility with GMT400 platform?

    Umm, the 454SS had five lugs. I thought they shared the same frame with the regular 1500’s(?). I believe the tow rating had to do with: 1-Engine torque 2-Drivetrain gearing But who really gives a crap about tow ratings for a fun cruiser? The guy wants to build a hot rod. I thought that I...

    OEM Cloth Seat Covers...

    wow! You guys are lucky! I have scoured time and again for replacement or NOS covers/foam for my truck - you would think that there would be a market for this (I mean iirc 1988-1994 got the same material and patterns); The best I have come across are the (ugly imho) covers offered by LMC - but...

    Do shorty headers add any tone and power to a stock l31 with a super 40 2 into 1 muffler?

    Would you (please) be able to tell me if those (factory installed) van exhaust manifolds are the same as the C/K1500 would have received? When I first got this truck, I contemplated getting some headers, but I wanted something trouble-free, and it sure doesn't get any more trouble/headache-free...

    88-94 vs. 95-98 Interior Debate

    I think there are definitely pros and cons for each generation of interior; I had a civil engineering field job in the summer of 1997 where I got to drive a brand new 1/2 ton (very basic; tan cloth interior, 305/auto), and I remember being "wowed" by the new interior; That engine seemed really...

    Truck Value- 88 GMC c1500 2wd

    Cool truck!! (I see you changed the mirrors from the original chromed ones) My grandfather bought an '88 when these first came out; I believe it was a 1500/2wd/auto - but it was the EXACT colour scheme!! The truck I own actually replaced his '88, which was passed on to one of my uncles - as he...

    Driveshaft yoke comparison between 4L60E and TH400

    just a small correction on the highlighted; The 1963-1970 Muncie transmissions all used the smaller output - BUT(!) the 1970 M22 placed in Chevelles(?) had the larger output (and corresponding revised tail housing); The 1971-1976 Muncie three speed (common in 73-76 square bodies) kept using the...

    What carb is this its two barrel i thought that 350's in 82' had Quadrajet

    I am glad to see members here know thier stuff! Those 2GC two barrel cars are the most common stuff from the 1970's - iirc they can rival our TBI's for CFM ratings... seriously. As to the Dual jet, the first version (a Quadrajet with the secondary side unfinished/closed off) was only done for...

    Why no TBI Engine thread?

    I enjoy reading the TBI discussions; I intend to keep my truck stock looking, and running the OEM computer; I have understood that our heads don't flow well, but that goes along with the tiny cam, and measly (cfm size) throttle body. I would love to have more power, but more power requires two...

    1990 GMC

    Congrats on the great looking truck! I say, leave it as-is - in that condition, and that low mileage, I'd be hard pressed to change it. But as others have said, it's your truck :)

    GMT floor mats

    when I started looking into replacement mats for my truck, I hit proverbial roadblocks at every turn - those "Holley" floor mats must be a recent offering, becasue when I ordered ACC mats, that wasn't an option. Now, my truck has had from day #1 (as far as I can remember) carpeted mats; It's...

    93 Factory Radio repair options?

    This was my gut reaction when I read your post. Is there any way you can test another head unit, to see if therein lays your issue? I do not believe that the CDM controlls this, but as I have understood it's the "brains" of the stereo - the functions are separate from the "brains". I recently...

    OEM part number; original vs replacement

    Thanks for your reply, I will remember this when it warms up outside, and I revisit the steering components. This guy is a fourty plus year career mechanic (he was supposed to have retired over a decad ago!) - I have absolute confidence in his assessment of the alignment.

    Unopened cassette

    I have these for a couple vehicles, they are pretty cool; It transports you back to when the vehicle was brand freaking new!

    OEM part number; original vs replacement

    It seems as though I had a misunderstanding that was increased with the very first reply I received. This post is what got me to re-look into this: This one really rang with me, so I looked into it: This is the design of the part #26016461 for 1988-1992 trucks: This is the design of the...

    OEM part number; original vs replacement

    Please allow me to clarify; When I bought my truck it had an original design (and probably the original built-with) idler arm in place; This truck is incredibly low mileage, and has had the alignmnet done, and service parts installed in the past; When I got the truck saftied, it had a...

    OEM part number; original vs replacement

    where did I say that? I have no doubt that the design was changed, then after the original part was (as pink suggested) ten years old, the second version superceded the first one. GM does this all the time.

    OEM part number; original vs replacement

    Yes, it was perfect; The mechanic that replaced the idler arm (he was doing an insurance safety inspection for me) told me that the design had changed from the original (twenty one year old) part that he removed, and that was why the steering is clocked slightly different. Many of these replies...

    OEM part number; original vs replacement

    the alignment is nuts on, but to keep it simple, the revised design idler arm clocks the wheel; the alignment was checked after. The only item that would warrant a re-alignment is the fact that the steering wheel isn't pointed straight when the wheels are. an alignment is straight labor that...

    OEM part number; original vs replacement

    First, Thank you for replying. Forgive my ignorance, but were you trying to be funny on some level? If not, who is "we"? Can you tell me the physical difference between those teo part numbers?

    Unopened cassette

    That's really cool!! If it wasn't dated for my1993, I'd offer to buy it! I'm now going to try to remember to start looking for a 1992 version of this tape!!

    OEM part number; original vs replacement

    I was wondering if someone with access to this kind of information might be able to offer me some help. I got my truck (1992 Chev K1500) saftied after buying it; There was play in the idler arm, and it needed to be replaced. I got this done by an old friends dad - because he has leaway that a...

    Carpet color?

    Here's my suggestion (I didn't see anyone else sugest this, which surprised me); Go to the ACC website, and write or call them requesting a couple samples. They may be able to simply tell you based on the interior RPO colour code. I did this before ordering carpet for my truck, and they promptly...
