one of your combos is not going to work being the rear end width is 2 inches different.
our car has 12 with 5" bs and a 54.5" and will need small spacer for a total width of 69 +/-
hope they both work out

Well Im @ a 6''BS on the rear, 57'' flange to flange. You are at 5'' @ 54.5''. Correct me if Im wrong but you add an in from both side to compensate for the bs difference and it would be 56.5'' F to F. Thats a 1/2'' difference that can be made up in the wheel well. I should have a 1/2'' on each side. With a 6'' lip on the outside and a 57'' housing that puts me @ 69''as well. PLease follow up with your opinion or input. Thanks-K
