3/4 ton members...question about late model wheel retro-fit - The 1947 - Present Chevrolet & GMC Truck Message Board Network

superchevy · 11-26-2004, 07:59 PM

I was thinking about putting late model '04 Chevy/GMC 8-lugs on my '77 C-20. Is this possible, or is it only the '02 and earlier 8 lugs that will fit?
Thanks for the help,
SC

From what I have seen in the 67-72 forum they should fit just fine. A lot of the C20 owners there are running them. I can't see why they wouldn't work on your 77....

check the center holes for hub end clearence but i think that the 3/4's never changed (unlike the 1/2 tons, damn it)

I'll find out for you tommorow, I heard that if you have a full floating rear end you may need to get the wheels bored out a bit...

I've got a set of 05 steel wheels I can try on, and let you know.

Would you be willing to trade center caps with me?

I'm just storing the steel wheels for now, I lent my wheels to my grandfather becuase he needed new tires and wants to make a trip down south. I just bolted my alloy wheels to his truck and brought his steels home. Unfortunately, my center caps are for a Chevy, and I have a GMC, lol

Lets see if they are sold first. If someone wants Chevy caps rather than GMC and your are in perfect condition I'll trade ya....

All 8 lug Chevy wheels, steel and aluminum, have the same offset and hub center size, regardless of what model year they are. Ford did the different center hole thing.

Dodges center hole is alot bigger than GM but its bolts up.

They are brand new, bought the 05, then pulled the alloy wheels off immediately as the company does not allow them
