Rallyes

The "old" center is the "mexican hat" style. It was the ~71 and earlier cars.
LBP for the E bodies, SBP for the A bodies. ~71-72, The SBP got the "acorn" style (the one you don't like).

so, you can find LBP or SBP in either style, depending on your stud pattern needs.

Some ebay sellers sell plastic centers for ~ $70 a set. Way cheaper than $70+ each for OEMs. They look perfect at a glance.
