Selection of a body after mkt rims?

scuba0331 - If you're talking about the classic Centerline Autodrag style wheel, they should be able to make this wheel in just about any width and offset you need since it's a 2-piece wheel. You just need to measure very carefully to make sure your offset is correct to center the wheel/tire in the wheelwell with your B-body rearend.
Of course, you can also get the B-body rearend narrowed to A-body width or narrower.

These are the ones I wanted and they are a no go unless I narrow the rearend. I don't think I want them that bad as the car is just about done! lol

I may go with the Classic Cragar SS as there are a few more back space options. I need abut 5.75 for an 8 inch rim.
