    Aftermarket gauges in dash

    I'm sure someone's done this before, but this is how I did it. Two 52mm gauges fit perfectly in the aftermarket radio delete compartment. Compartment from Crutchfield. Dual Gauge mount from VDO.

    Brief write up about removing dash/heater box

    I imagine 90% of these trucks have mouse pee in them too. They need taken apart and cleaned anyway after 30 years

    Brief write up about removing dash/heater box

    It's a big job to pull the dash, but I really had to. The main harness got damaged somehow...maybe mice. I think you could replace the heater core and evap core without removing the heater box. Once I had the dash out though, it seemed easier to pull the box out to change the cores. The box had...

    1993 Silverado replacing the dash questions

    Your evap core might look like this. I can't see light through any part of it. There is dirt down in the fins, and I doubt it would flow any air at all. I guess I could try to clean it, but the system has been open for who knows how long and a new core isn't that expensive

    Brief write up about removing dash/heater box

    I took mine apart for wire harness repair and cause I suspected the evap core was clogged full of mouse nest. 100% correct assumption. Not only mouse nest, but moldy dirt was completely sealing off the evap core. No chance of any air getting through that core. So yes. After 35 years, we are...

    1993 Silverado replacing the dash questions

    I currently have my dash out. When I removed and disassembled the heater box, the evap core is completely sealed off with mold and dirt. No chance it would flow any air or cool efficiency. I'm replacing the evap core, heater core, and all three actuators. Plus I will clean the inside with...

    Brief write up about removing dash/heater box

    I don't actually have a write up, but I would warn anyone that the plastic tabs are probably going to break. I have worked on a different 1990 truck interior and a 92 Camaro, and GM was really at a low point with regard to the quality of their interiors in the 1990s. Expect to break some plastic.

    Mark IV 7.4L engine 1989 K3500

    Its a 1989 K3500 that was advertised as having 108k miles. I bought it based on pictures only for $1200. I think I got lied to and they have swapped out the odometer. Win some, lose some.

    Convert TH400 to manual transmission

    I have a 1989 k3500. It is 4x4 7.4L with TH400 mated to the transfer case. Will the NV4500 bolt to my transfer case? Will I need a different transfer case also? Has anyone one made a thread about swapping out TH400 for a manual?

    Np241c transfer case

    I want to convert my truck to manual shift. Will any transfer case from a chevy truck work? Does the transfer case need to be specific to the axle gear ratios? I have a 1989 7.4l with TH400 Will this one work? https://www.facebook.com/marketplace/item/716619466786331/?mibextid=dXMIcH

    Possible replacement for Hot Fuel Module

    First, how the hell are you smart enough to make this. Second, what do you charge for it? Mine just smoked and I can see a little crispy transistor thing inside it. Also a melted spot on the outside if you look close you can see it. Edit: I pm'd you

    Quality Cab Corners ?

    I ordered drivers side cab corner, rocker panel, and one wheel arch. They all fit like ****. I cut them apart and just used specific bends in the right places. After I did the wheel arch, I learned the valuable lesson to only cut out the minimum amount of the rust, and cut up the aftermarket...

    Rust repair on work truck

    I bought used OEM fender flares from a junkyard to cover up rusted wheel wells. I held the fender flare in place and traced it. I wanted the metal repair to be hidden under the flare. I bought a patch panel. It was about $35. I should have saved my money and just patched in pieces of 18 guage...

    98 K2500 7.4 upgrades

    I used Edelbrock EStreet 2 which was their cheapest system they offered in 2016. I have always had an annoying dead spot just off idle. Seems to perform well in all other aspects. The system is no longer supported, which means the app no longer works on current Android OS. Honestly, I think the...
