I also made a couple junkyard trips... Found a factory 3-piece slider window in good shape.

And picked up the new rear axle - 14SF from a 95 K2500, 6 Lug, 3.73s (will be re-geared) and a G80.

I've had a few people ask why I'm going from 8-lug back to 6-lug... Well, the primary reason is the 8-lug Dana 44 hubs set the wheels out 1-1/4" wider on each side, so 2.5" of more track width. Combined with the backspace offerings of 8-lug based wheels, I'm sitting at 4-5" wider up front, which honestly I didn't care for. The only wheel I could find that kept me where I wanted was the PY0s I had previously, and they are just simply too narrow and the ONLY option that kept the tires where I wanted them. So back to 6-lug I go. I'm not really towing with this, wont really be wheeling the crap out of it, etc. so the difference between the 14FF and 14SF is negligible IMO. Plus, this wheel/tire combo with these caps is just simply bitchin' IMO.

Once I was done screwing around admiring my tires, I spent 3 different sessions in the driveway blasting my frame with glass bead. It was dusty, messy, annoying, yet oddly satisfying.

Day 1 - Engine cradle and outside

And just because it's cool, GM part number, date stamp and stamped VIN in the frame.

Now you are up to date :) Next step is pulling the springs and axles and coating the frame, then blasting and cleaning the axles, and re-assembly will start.

I’ve always wanted to do a full frame restoration. Looks great

Where are you getting the g80 for the 14 bolt sf?
I need to get one for mine. I am holding off to swap my 10 bolt because it's g80 and the 14 is not.
Thanks

It already has one in it.

If I swap it out for a different traction aid, I would get a Detroit Tru-Trac as they are helical gear and much more durable.
