    R12 Replacement

    With a factory R12 systems, either pay the premium for actual R12 or just do a 134a retro fit. There are some factory R4 compressors from the the mid ‘90s that used 134a from the beginning, so it’s very much possible. Just ensure that all the O rings are replaced with the correct style, the...

    Does anyone make 17" aluminum 4x4 Rally wheels?

    Skinny wheels can be made to look nice too. You should be able to get away with using 33 inch tires on stock or stock sized wheels without having to resort to shaving and lift kits.

    ‘83 ‘84 GMC Grille on eBay @Streetdreamer

    After seeing these prices, it’s depressing to think about how many decent ones likely got tossed into the dumpsters back in the day to install those cheesy JC Whitney grilles that look like they belong on a commercial AC unit rather than a truck. Hindsight is always 20/20 I suppose.

    Clear coating over patina: anybody done it?

    Punch a hole in the power steering feed hose and the engine bay will shine itself up. Lol One day on my ‘85 C10 I noticed it took every thing I had to back to get out of my parking spot. When I opened the hood, the power steering pump was dry but the engine bay looked the freshest it had been...

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    Interesting. Another thing I’ve learned is that there are Mopar automatic transmissions that have the same kind of weep hole such as the 48rfe on third gen Dodge Ram 2500/3500 pickups. Clearly GM is not the only ones to decide to use this odd vent mechanism. Granted, the inconsistent usage of...

    Does anyone make 17" aluminum 4x4 Rally wheels?

    Totally agree. I’ve had a few as well driven the GMT900s and post 2013-2019 “K2” trucks. I still prefer the 800 to both of them. The 800 is new enough to have an engine engineered specifically for TBI use and not just a retrofitted small block like the late production squares and GMT-400s had...

    Does anyone make 17" aluminum 4x4 Rally wheels?

    I ran some 34 inch super swampers on some PY0s once. Being a GMT800, I had to put a leveling kit on the front end and shave the bumper skirt a little. The truck handled like a boat at highway speeds but the stance looked awesome and that truck could make it through mud holes and ditches that it...

    Does anyone make 17" aluminum 4x4 Rally wheels?

    I like the factory Rally wheels a lot aside from only being available on 1/2 tons. I will say that the trim ring retainer tabs have been the bane of my existence in some cases. I’m about to just rtv one on. Odds are I’ll be able to rip the trim ring back off when it’s time to change tires again.

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    As much as I hate resorting to “unauthorized fixes” I might just make an exception for this. I just wish I knew why it is set up this way in the first place. It’s weird how only the full size trucks have this and not the various cars of similar vintage. Does towing generate more pressure in that...

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    New update: After about a week and a half, the yoke weep hole leak has returned, though the puddle is much smaller. I don’t know if I should just plug it or live with it. The amount of fluid lost seems pretty marginal but it’s very annoying regardless.

    Does anyone make 17" aluminum 4x4 Rally wheels?

    Now that I think about it, GM always seemed to limit the 8 lug stylish options on older trucks. There was never a factory 8 lug Rally or aluminum wheel on the squares and never an 8 lug “saw tooth” on the GMT400s.

    Does anyone make 17" aluminum 4x4 Rally wheels?

    if you’re unsure if a wheel is aluminum or polished steel, and magnet will let you know instantly. Aluminum isn’t magnetic.

    Does anyone make 17" aluminum 4x4 Rally wheels?

    The GMT800 era PY0s do look much better than the comparatively giant 18 inch and larger OEM wheels on newer trucks. My only real gripe about them is the little plastic guards on top of the lug nuts. They often strip and cheapen the look of an otherwise attractive wheel.

    Does anyone make 17" aluminum 4x4 Rally wheels?

    Those came factory on my 04 2500HD. They look great on that truck but look a little too busy on a square for my liking.

    Does anyone make 17" aluminum 4x4 Rally wheels?

    I’ve always preferred these. They heavily resemble the factory GM wheels that appeared on some of the higher trim five and six lug squares. They also have a center hole big enough to accommodate Warne style front lockers.

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    New update: It has been nearly a week and the transmission still seems to be holding its fluid after the O ring change. I guess I’ll leave the weep hole for now.

    Leaking transmission pan plug

    Hopefully that fixes it for you. I’ve been straightening out warped OE pans, out of fear of getting an out of spec aftermarket pan. If yours holds up after this I might get my faith in after market pans restored a little.

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    Update: I’ve replaced the O ring inside of the cup. I will watch it the next the few days. If it still leaks, I’m going to plug the yoke.

    I hate the power window and door lock switches

    The ratcheting crimper is a game changer. I remember the absolute misery of trying to crush butt connectors with lineman pliers or channellocks. Soldering is also a tedious affair in tight spots and isn’t really super protected against vibration damage. My ratcheting crimper (I forgot the brand...

    I hate the power window and door lock switches

    I have experimented a lot with different crimping techniques. The best that I have found is to use ratcheting crimpers with heat shrink style butt connectors. The plastic melts onto the wire insulation and "grips" it, this makes it harder for vibration and movement to cause a wire to back out. I...

    Leaking transmission pan plug

    I would try an appropriate size rubber washer and teflon tape on the existing bolt. While it kind of defeats the purpose, as a final resort, you could just JB Weld the drain plug into the pan if you do not want to go through the trouble of changing the pan again. I have never really worried too...

    TH350C/700R4 yoke weep hole: To plug or not the to plug?

    My TH350C on my '85 C10 like spit a large amount of fluid out of the yoke weep hole when it sits for about 2 or 3 days. It is my understanding that an O ring needs to be replaced on the little cup on the output shaft. I will go ahead and do this, but in the unfortunate case this does not stop...

    Clear coating over patina: anybody done it?

    Beautiful result. At quick glance, I’d almost accuse it of being a repaint. Unfortunately, the trucks I’ve gotten either didn’t have enough paint left to polish or had paint missing in several places. Mother Nature and Father Time have not been kind to ‘80s GM paint.

    Clear coating over patina: anybody done it?

    Clear coating can often create more problems than it solves. I think temporary protective coatings like the various waxes and wax-like products on the market are better for preservation than more “permanent” products like the various clear coat paints. It sounds easy enough to just “cap”...
