Anyone know lug sizing for 14 bolts? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all. I recently got ahold of a 14 bolt FF and it's in a kinda of crappy place in my yard. I think I'm just going to use a jack and put some wheels on it and push it around but 1 thing occured to me; I don't have any spare lugnuts to bolt wheels on with. I thought I'd try a couple of nuts from my '69 as a temporary thing and it turns out they won't fit!

Anyone feel like clueing me in on what I need? Many thanks,

Greg

I think they are 7/16, not sure though they had more than one lug size. I think they were 1/2 and 7/16 until later when they went metric.

14 bolt rears use 9/16 wheel studs.

Thanks guys, I'll check it out and post what I find.

I'm going to swap in a front end from a '72 Longhorn so I get disc brakes. Any ideas on getting the lug sizing to match front to back? I could probably get the holes in the rotors redrilled and matching studs pressed in but are there any other years of factory rotors that would do the job?

Many thanks,

Greg
