Does anyone know the front wheel bolt pattern and lug nut size (socket size) for a 1964-ish GMC 4000?

I have a 65 GMC 4000 with the 10-lug, 8.75" bolt pattern and 6.25" center bore with 1 1/8" lug nuts. hope that helps.

Hi,
I think this one is 5 lug up front, although I have no idea why they would be different...
What's the width of your truck measured at the outside of the tires?
Thanks,
Pat

think i answered this on different post - but 88" at front and 94" at rear (approximately).
