Depending on the size of the spacer you need to run, an "adapter" is an easier and safer option. Wheel adapters bolt on to the original studs and have new studs in them that you bolt the wheel to.
One thing to keep in mind is that to install studs in the rears it quite a trick to get the regular length ones in since you can't get at the back of the spindle flange....
If you're pulling the rears apart, no problem, but without pulling the spindles out, 1-3/4 is pretty damn tight, 2" might be possible with some cutting, 2-1/2.....
That's probably what's on mine. Not the best picture but what's handy right now.
You realize you won't ever be able to put rally wheels with the center cap on!
As I recall the holes on mine needed to be enlarged. Will these studs fit in the existing holes? If not be careful. I got quite a lecture from my local guy about not just drilling bigger holes. He had a jig to make sure my wheels weren't off center due to holes not being on the stud circle. This of course was done with the spindles out. I would recommend you have a machine shop do the work, unless you already have the skills and equipment. Wouldn't want the tires to go bumpty bump.
Also agree with what Mooser said about getting these into rear. May not be possible with this length.
I had tracdogg2 install a set of long ARP studs in the rear axels of my '81. The holes have to be enlarged in the hub to install these studs. I searched the forum and some have put longer studs in by cutting an access hole in the backing plate to install them.
I am just going to change the e-brake cable brackets and not use the spacer. I have the trailing arms out and the entire rear is apart. I do not like the idea of a different size lug. just wanted longer and it seems that is not available.
