Not sure yet. I think I will. What would be the value of the cragars? I really have no idea

Probably not a ton. But someone might want them for their old hot rod.

Either my chevy pattern is a bit off or the wheels drilled to tight but i cant get them to fit. They're off by 1mm at 3 of the 5 studs....

No, they're chevy, 100% sure.
And as you can see the cragars have oval holes, and they centre themselves with the lug nuts that go IN the wheels.
Not sure kow how to make them fit.
Airtool?
Enlarge the boltholes from 12.5 to 13mm?
Pfffffff

This is for what it is worth:
https://en.wikipedia.org/wiki/Wheel_siz ... %20inches).
I've had 26 Chevs and had lug bolt problems with a lot of them with the bolt not being straight up being pretty common.
The URL above does cover a way to check but there are a couple of other ways with making a cardboard cutout the dia. of the bolt circle being the easiest... probably and overlaying it on the bolt centers being another. Using a compass or divider measuring from the center of one bolt to the two opposite bolts and duplicating that around the circle being another.
For various reasons I am not a big supporter of adapters either as they have a tendency to fail or be out of dimensional tolerances.

Show us your front and rear disk face where the wheel bolts up to. And the hub where the disk slides over also f you can.

Looks like you've already had a different bolt pattern done at some time. I was hoping this wasn't done yet and you could just get your machinist to put the new bolt pattern in between the factory holes.
Are those threaded in studs or press in ones ?
I wonder how strong they'd be if a third bolt pattern was done ?

With a 3rd bolt pattern they would be lightweight racing rotors.
