    What’s wrong with my axle tubes?

    An axle saver bearing may have been used because bearing was rotating in the axle tube. As mentioned above, they don't cost much. Check out RockAuto. #1559 axle saver bearing/seal #6408 OE-type axle bearing

    3/4 semi floating axle to full floater swap

    Yes, slowing down helps, but it's not practical or safe to drive much slower than the traffic around you. GM didn't put 2.56 and 2.73 axles in our trucks to help them carry heavier loads, they did it for MPG ratings.

    Funny sorry about my interior

    Maybe it's there to protect the socket???

    1982 short wide bed, model specific camper $3600

    Nice looking truck from the pictures you posted. I'm surprised to see such a low price. My 82 Custom Deluxe is similar, but I replaced the 250-six and 3 speed manual with a 350 w/ auto trans. May sell it later this year and was planning to ask a lot more than that!

    GM #471634 motor mount "clam shells" for "K" trucks

    FYI, that's not rust on the parts, it's red oxide primer! Don't know why I didn't completely paint the undersides.

    GM #471634 motor mount "clam shells" for "K" trucks

    For 79-83 K10-20-30 trucks with 305-350, and 82-83 K10-20-30 trucks with 6.2 liter diesel. May fit other years, but my parts book only went up to 1983. Bead blasted and primed inside and out. Painted on the outside. I tried to use them on my 82 C10, but they aren't as tall as the 2WD...

    Cracked manifold - looking @ headers and exhaust on a budget. Suggestions?

    And that's after you jump through all kinds of hoops to make them fit! And that hi-temp paint? Plan on repainting every 1-2 years, or just living with the surface rust, especially if the truck is parked outside. Again...

    700R4 1-2 shift issue, please help!

    Before I removed the valve body, I'd watch throttle valve movement while a friend opens and closes the throttle linkage. And make sure that fast idle (choke on) is not set! Then manually move the TV lever to make sure the cable is moving the valve fully open, and that the spring is fully...

    APB - Check your cowl seam seals!

    I suggest scraping out the old seam sealer as much as possible, and then cleaning the area to be repaired with wax and grease remover (AKA Prep solve). Then lay down a wide bead of good quality seam sealer. This SEM product has worked well for me...

    APB - Check your cowl seam seals!

    On my 82, they did a terrible job with the seam sealer in some areas, allowing water to drip down behind the fuse panel. That eventually caused rust to develop on the fuse connectors, and rusted out the bottom of the kick panels. It's fixed now, but all that trouble because of some GM assembly...

    3 alternators in less than 6 months

    What's important to know is the amplifier current draw when the volume is cranked up. Then go from there to determine the required wiring gauge and alternator current rating. Of course you also have to factor in current draw from lights, ignition, A/C heater blower, etc. To do that you will...

    Mid-range head options

    Not sure if this is your problem, but I once had some old heads that would leak oil down the valve stems after the engine sat for a while, which caused a few seconds of exhaust smoke on startup. After that, no smoke at all. These were earlier model heads with no oil control except for o-rings...

    This genuinely offends me

    The non-slip pattern allows you to keep your feet securely on the dashboard. No more slipping on a vinyl dash cover!

    455 Olds in place of 454 in 76 GMC (frame to engine mounts?)

    I found P/Ns 464715 and 464716 on GmPartsWiki.com when searching for "bracket, engine mt diesel" for 1978 light truck. I then did a Google search on the P/Ns. This page came up as well as some others...

    Rock Auto buyer beware

    I've bought a few of their close-out parts over the years. Have a good stock of small bock gaskets -- water pump, t-stat, timing cover, fuel pump, valve cover, etc, some of which cost literally 20 cents on the dollar. Bought a USA-made master cylinder from them that was in an old, faded...

    Posi screws in your Square

    Reed and Prince screwdrivers have a point. Can't think of anything the screws were good for.

    I melted a Piston, 250 Inline 6.

    Glad you stuck with a six. I did the 250-six to 350 deal several years ago, and it was not trivial. Had to source different motor mount "clam shells" and spent lots of time modifying the wiring harness. All I had was the basic 350 itself, so needed exhaust manifolds, down pipes, water pump...

    Seam Sealer???

    I don't know what GM used back then, but I'd bet the current sealers are a lot better. I like this SEM product: https://www.amazon.com/SEM-29372-Gray-Seam-Sealer/dp/B00BI281IC/ref=sr_1_3?dchild=1&keywords=sem+seam+sealer&qid=1590703614&sr=8-3 It's available in several colors, and you can buy...

    Posi screws in your Square

    Back in the day, Hewlett Packard and others used Pozidriv screws on electronic test equipment that I worked with. Using them and the proper screwdriver makes you wonder why they aren't more popular. Pozidriv is to Phillips, as Phillips is to straight slot.
