    Which posi unit do you like?

    The posi units with spring loaded clutches always work well on the street, we used to have to use an additive with those before synthetic lubricants. They will hold up fine unless you’re using slicks. A locker will be radical on the street, it’s really for race applications. I’ve got TruTracs...

    NP203 transfer case availability and rebuild

    The 32 spline input gear also has a bigger bearing that means the case has to be bored for the larger bearing also… it’s not a tough job for an experienced machinist but another cost involved. I spoke with that retailer when I thought about rebuilding my 203, they didn’t have the chains in...

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    I believe we touched on this in your previous post. You may need to loosen the motor mount to frame bolts to get a little wiggle room for the crossmember to line up. I believe those crossmember bolts should be 7/16” diameter bolts not 1/2” also. The drive shaft angle may require the reared to...

    Is small front cross member movement normal

    You probably need to remove the steering box to really inspect for cracks. There should be no movement anywhere in the crossmember.

    Up on the roof

    My shop building is 25 yrs old and those roof screws were shot. I replaced the #10, 1” screws with #12, 1 1/2” Right at 500 screws total, that was a workout!

    Death wobble, or bad wheel balance?

    You’ve got a bad ball joint… definitely start there

    Rim compatibility

    They’re out there but really $$$ expensive… especially the 8 lug versions. https://www.uswheel.com/wheel/16271/us%2Dwheel%2Drat%2Drod%2Dseries%2D651%2D8%2Dlug/?finishID=405

    Cab leaking

    In the bottom corner of the windshield channel on each side there is a small drain hole, it’s under the gasket. If this hole is blocked with debris or sealants the water will back up and get in between the two pieces of the windshield flange.

    Used two post

    You really want a footer under those posts. They usually are 3/4” diameter concrete anchors, the length would be for the thickness of the concrete. Big box stores may have those, not sure.

    Rear disc conversion

    I looked into it when I began my rebuild on my K20… In my opinion that conversion is a lot of money and effort for very little return

    Rim compatibility

    I just like to explore all my options… before I screw something up. :) These are available from a couple of different manufacturers in a couple of different sizes & styles. 17s just made way more sense to me as my late model truck uses them.

    4L80 on FB Market Place

    No, it was gone as soon as it was listed.

    Rim compatibility

    I ditched the 16s for 17s, I am going to use one of the 16s for a spare.

    Speedometer cable extension???

    I’ll be looking for one also, as I made the same type of change. These folks look promising https://mrspeedometer.com/products/gm-speedometer-cable

    Odd “knocking” noise at high RPM while WOT

    A vacuum gauge can be helpful if you’re not sure about the timing also.

    Little wire cut from bulk head what did it go to? Looks to have white stripe with it but can’t tell other color?

    These are the type of terminals that were used in the ‘70s fuse boxes, they available from several places. I’m not certain if yours uses the same.

    Replacing front brake lines - remove proportioning valve?

    There are different sizes/styles of vise grips… When you get ready to put it back together some Anti-Sieze on the threads of the fittings will prevent it from happening again.

    Hello from kentucky

    Correct source for ac vacuum

    Yep, you can get those fittings in a couple of different configurations. I just installed one to supply the brake booster and transmission vacuum.

    Can you believe this???!!! TC/NP208 Adapter/700R4 trans crossmember mounting/question?

    The crossmember bolts flat to the bottom of the frame, there should be some spacers on the TOP of the frame for the proper length bolts.. don’t sweat that though if you don’t have them. The third pic shows the proper adapter mounts, you have the rubber portions on the bottom also correct? Leave...

    Dana 44 front axle issues

    Yes, there’s probably differences between the two, I’m definitely not schooled in that area. I used Eaton 912A557, it required a bearing with a larger inside diameter. Let us know how it performs when you get it in, my truck is still months away from being mobile.

    Dana 44 front axle issues

    I installed a TruTrac in my front 10 bolt, haven’t had a chance to try it yet but they get great reviews. If you’re going with the TruTrac it uses different size carrier bearings than the original GM carrier.
