Advice Needed Drag Racing w/ Cragar SS

I thought the Cragars were shank style rims

I looked at the site to see
Series 08/61 S/S Super Sport

I see you are in Middle Tn, >where
I'm in Smyrna
The uni-lugs are, and some of the direct drills are. My fronts are, but the backs weren't available with the shank style. Go figure. Yeah, just down the road in Murfreesboro.
