    Making changes to a 10 bolt rear

    Gonna make this posting to see what you folks think. Been toying with a SF 14 bolt swap ( see recent post on axle swap), but this could be expensive on my limited income (I'm retired). So, what I thought of, is this. I have a 10 bolt rear from a previous C10 project ('86) that's complete, drum...

    Rear axle swap 10 bolt to sf 14 bolt

    I've read the 80+ pages of the stupid axle sticky and seeing as how most of it has been captured by the 4x4 crowd, I'm gonna ask some questions for us 2 wheelers. First off, my truck is a 2wd. '89 Cheyenne, with a 3:08 10 bolt. I've located a rear from a C2500 2wd that has 3:73's. I know I'll...

    Plastic/nylon pieces for grille screws

    Does anyone know what the inserts are called for holding the grille mounting screws? My grille has been removed so many times that the screw retention is becoming minimal to non-existent. I have to remove the grille once again, to replace the headlamp buckets, and I'd like to replace these...

    What is this connection?

    There is a connection on my radiator, above the ATF upper line and below the coolant overflow connection, that is threaded and capped. What's it for? And does anyone happen to know what the thread size and pitch might be? I'd like to use this for my LS bleeder line, which is currently spliced...

    Brake code ID

    Trying to ID the brake system on my '89 Cheyenne. The SPID shows a J code of J50. Can this be considered the JB5 system? It's the only J code on the SPID. The vacuum booster is the larger unit. There is no F44 code, so I'm assuming the truck is the light duty variety. Anyway's, I need to improve...

    Hi/Lo beam situation

    So, after owning/driving my '89 Cheyenne for a couple of years, last Friday was the first time to drive it at night. Went to use the high beams, and got nothing but a wiggly shaft (doncha just hate that?). Got under the dash to take a peek, and found the actuator rod not engaged in the dimmer...

    Door striker

    Are the nut plates for the door strikers fixed in place or are they loose? I need to replace mine, so before I just unscrew them, I'd like to know if I have to pull the interior panels off of the body. Thanks

    '93 instrument cluster repair question

    The volt meter in my cluster has started to do a wierd thing. The voltage will fluctuate from normal charging voltage to about 8.5-9 vdc. The alternator output is a constant 14+vdc, and the battery voltage is steady. I'm going to pull the cluster and check for constant voltage at the connecter...

    700R4 id help

    I'm trying to identify what this transmission came out of originally. It was transplanted into my '89 Cheyenne and I'm fairly certain it came out of an Fbody. The tag reads 2FTM. I can ascertain the 2 being 1992, and the M signifies 700R4, but the FT I cannot find any info on. A friend wants to...

    My '89 Cheyenne DD LS swap

    First off, let me introduce my truck. A plain Cheyenne with a tired and questionable 305/700R4 boneyard combo, most likely from a Camaro or Firebird as indicated by the trans tail housing and the wrong TV cable. Having fixed those problems, I've driven it for more than a year. But now, the...

    speedo bezel repair-my way

    On a recent vacation to Maine, I found a Pull-a-Part yard, and decided to have a look for a cluster bezel for my '89 Cheyenne. Found one that looked pristine, so I proceeded to remove it. Don'cha know, that when the 4 corner screws were removed and the bezel was loose, the light switch fell off...

    AC accumulator

    Can anyone tell me the thread size for the outlet of an a/c accumulator for a 1989 Cheyenne? I'm going to be making my own lines for an LS swap. Thanks

    4L60E 2-4 servo

    This is just a point of interest to anyone considering a Corvette servo for their transmission. For my last swap, I used the Corvette 2-4 servo and found the 1-2 shift quite firm (at least for my liking). The swap I'm doing now ('89 Cheyenne) I was just going to use the stock servo, with some...

    plastic threaded hole repair

    Several of the holes for my dash bezel hold down screws are stripped from previous owners. Is there a fix for this? I've been thinking on using a moldable epoxy to fill the holes and then run the screws in (after coating them with some sort of release agent) but not sure if this is a viable way...

    Radiator module for a soon to happen engine swap

    Gonna be changing the 305/700r4 in my '89 Cheyenne to an LS/4l60E this fall. In order to get ready, I figured to replace the existing radiator with a new one, and find a cooling fan setup. In my last swap, I used a Windstar fan assy. which worked well, but it stood about 6.5" off of the radiator...

    305 or 350?

    In a quandary here. Don't know what I have for an engine in my '89 Cheyenne. The VIN (letter H) says it's a 305. BUT!! ... Bit of a back-story here. Bought the truck in late spring of this year. While making some needed repairs, found boneyard markings on both the engine and trans. Also...

    A steering box replacement

    After purchasing my '89 Cheyenne, this summer, I noticed a huge amount of slop in the steering. I joined this forum, and found that this is a common malady with this family of trucks. My initial attempt to remedy the situation was replace ball joints, tie-rods, idler and center link. That did...

    steering shaft 26015779

    Didn't want to put this in the Jeep steering shaft mod thread, but there is where this thread has originated. I had done the Jeep steering mod on my '89 Cheyenne but had reservations on its' retention of the steering column. When I posed that on that thread, Mr. Schurkey eloquently stated that...

    Brake swap question

    Does anyone know if the earlier 10 bolt, 11" brakes fit on the OBS 10 bolt rear? I have an '86 C10 rear axle assy. from a previous project that has the 11'brakes, just sitting on my garage floor, and was wondering if it would be worth the change on my '89 Cheyenne. Having recently joined this...

    7004R VSS situation

    Ever since the purchase of my '89 Cheyenne, I've had shifting problems (recently rectified w/TransGo 700 kit) and my speedometer hasn't worked. I've replaced the cluster twice and still no speedo. While the cluster was out, I disconnected the harness from the VSS and tested the wiring from the...

    Sonnax pinless accumulator pistons

    I'm putting the Trans Go 700 kit into my 700r4 trans because of a stuck TV valve situation. Does anyone know if the Sonnax pinless accumulator pistons will affect the kit's performance? Thanks

    TCC unlock wire

    I'm about to install a 5.3/4L60e combo into my '89 Cheyenne. I'll be using the LS stand alone harness and PCM, so the truck's ECM and harness won't be in the picture. What I need to find is the TCC unlock wire from the brake pedal switch. Would that be the purple wire on the switch? I actually...

    LS fuel lines

    I'm about to do an LS swap (5.3L) into my '89 Cheyene, which has a 5.0L TBI engine. The throttle body has the factory braided fuel lines. Will these lines support the higher fuel pressure for the 5.3 fuel rails, or should I just make new lines to connect to the existing hard lines that run under...
