Bolt pattern on 69 GMC 3/4 ton 8 Lug - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Momboy007 · 10-15-2008, 11:06 PM

Hello All,
Does anyone know the bolt pattern for a 69 GMC 3/4 ton truck? It has the 8 bolts, but I do not know if it 6.5" or what???
Thanks all,
Rick

My '72 looks like 8 x 6 1/2".

I can't promise that exactly; I was working by myself with a tape major and a flashlight.
But, I'll say I'm damn close.

Yes, 8 on 6.5"

OhioDan · 10-16-2008, 03:54 AM

I have a Dana 60, and mine are 6.5" also.

Back when Detroit figured standardizing was a smart thing all 8-lug pickups used the same lug pattern.

Sinister · 10-16-2008, 10:08 AM

My '69 C-20 is 6.5"

so besides the bolt circle what about the hub hole diametter differences?? Ford to Chevy vica versa??????

Sinister · 10-16-2008, 12:08 PM

One of my rims is off a F@rd and fits O.K.

prg machine · 10-16-2008, 04:22 PM

i've heard that chevy won\t fit ford cause smaller hole for axle hub?????

wolfgang_90 · 10-16-2008, 11:14 PM

after I think 1999 ford switched to metric.. (damn they've gone metric on us again) The metric one is like 8 on 80mm or something. Before the cut over, the ford rims bolt on to GM's and visa-versa. They are a little wider than the GM ones if I recall too.

my 69 C2500 has the 6.5. I measured it just last night.

onlyifihadachevy · 03-10-2009, 08:26 PM

the newer fords wont fit theyre off by a little and chevy and dodge r the same i thinks its 8 x 6.5 and most people agree so i would go with that

New chevy and dodges are the same because they use the same axles. And yes, there's a member here w/ the aluminum PYO's off of a newer chevy, and I've seen another w/ the chrome steelies in the long-step thread.
