Hey guys
We have a 70 Polara Custom 2 door hard top that I have to order some new wheels. We're looking at Torque thrust 2's and would like to know what size of back space in 15" fits the C body the best and fills out some of these big fender wells

 

Up to an 8" wide wheel you can use a zero offset.
if you want to squeeze a wider wheel yet (rear only) it would be best to look for a small positive offset like +5mm to maybe +10mm
This will move your tire closer to the leaf spring and give you good clearance from the fender lip edge.

 

thanks for the reply
