79 wheel swap

[Denbutt]

I'm wanting to do a wheel swap from a 2006 3/4 ton 4 wheel drive with stock aluminum 8 lug GM wheels to a 79 3/4 ton 4 wheel drive with steel wheels. The 06 aluminum wheel has the center cap with plastic nuts that thread on to the lug nut.

My issue is the studs. the 06 uses metric studs and I beleive the 79 to be standard thread. Has anybody done this swap? What did you do? Switch the studs or use different nuts? Where did you get them?

A longer stud wouldn't hurt with the aluminum wheels. Thanks in advance!
