Ran into the same with the threads and new nuts during my DG4 rebuild....i too thought it was just chrome slag until I found 1 note on the forum that the OEM studs are 3/8/20 NOT 16 or 24.....ODD pitch....

I thought they looked weird!!! That is a solid fact. Makes so much sense. Thanks Dave. Mine are pretty well 3/8-16 now.

Thanks Dale.

Fuses in. First systems check, good.

Truck, like most, had a dealer installed rear bumper originally. Shoulda probably gone with some type of period step...but I'm a sucker for a rear sport bumper. This was an NOS painted bumper that I found. Chromed up nicely.

Eric got the cowl on. Like all the other paint work...looks great.

And I should have highlighted this earlier, but Pete hooked me up with an NOS parking brake handle. Thanks Pete!

I'd held off putting on the "Tacky Tape" on the expansion valve because...it's sticky and picks up stuff. They come from Old Air in 15" strips. Should be 20" IMO. I bought two rolls and used about that much.

Also, coffee can style A/C vacuum reservoir is on.

The rest of this week's updates are really just 'in progress' reports. I am waiting on a few parts. But also I got lucky and scored some.

First I am so happy to have NOS ribbed heater hose. Just having trouble with tower clamp sizes. Can't seem to come up with 3/4" or 1" tower clamps per the A/C manual. I have and can get my hands on 1-1/16" or larger. I even have a few nice originals with a workable date on them. 1-1/16" will work, but would like to get the smaller ones if possible.

Been looking for the correct NOS muffler for over 3 years. Had a replacement # NOS muffler from about '75 that was super nice, but not the factory correct finish. Unbelievably the right muffler popped up on eBay a couple of weeks ago. A little bit of shelf wear, no box. But generally cleaned up nicely and will go well with the NOS tailpipe.

I have been able to put together a nearly complete set of NOS hangers and hardware...except for the two piece hanger/clamp that goes in front of the muffler that feels effectively like unobtanium (see pic of original version below). I've got some ideas for managing it...we'll see. Again, waiting on the mail.

I also would love to put together a set of the original swing arm, one bolt exhaust clamps. So far zilch on that.

If the rest of the exhaust hardware gets here and we can get it hung...and we can get the cooling system together. We are basically at crank, put hood on, paint tailgate letters, install tailgate, high five.
