    changing TH 350 oil pump seal while still in truck?

    I like this idea. I'm concerned why that seal would be leaking anyway. Thanks!

    changing TH 350 oil pump seal while still in truck?

    I'm going to do a 305 to 350 swap on my '79 Jimmy and want to fix the weeping oil pump seal behind the torque convertor while I have the motor out. Buddy of mine said don't do this unless I pull tranny and stand it up on it's tailshaft. First I've heard of this but his reasoning is that...

    Which welder?

    I was having the same issue and I put Weld Aid lube pads on my MIG and this problem disappeared. https://www.amazon.com/Weld-Aid-Lube-Matic-Combo-Packs-Various-Available/dp/B06XYR7Z98

    Color wiring diagram

    Anybody have a colored wiring diagram for a squarebody (1979 K5) where the diagram matches the actual wire colors? I've got a black/white copy and but haven't been able to find one in color like this. For me, these are so much easier to trace things around. Have a starter that sometimes stays...

    Thanks for welcome. You guys pretty much summed up what I need to do, esp @Rusty Nail. Headed for the build threads now.

    Intro and is it worth fixing?

    Hey, new guy here from Central Texas. Just acquired this GMC Jimmy in a trade for some motorcycle mechanical work. I'm pretty handy with a wrench, but never really did any major body work. My question for the crowd here is this thing worth putting the money into fixing or is it a major...
