Offset springs in an early A

Resurrecting an old thread. Anyone have 15x8's on the rear of a early a (Dart)
without using the offset mounting kit? My wheel houses measure 12" and with a 1" of clearance inside and back and a 1" each side for tire bulge and a 8" wheel with the proper offset should work. I will probably get 15x7's just to be safe. tmm
