Does anyone have any photos of slotted mags on a 1968/69 Cutlass? I am wondering about the fit. Specifically the rear with the common 3.5" backspacing.

 

First, what "fit" information are you looking for? The backspacing number is meaningless without also specifying a width. And wheel diameter and overall tire diameter are equally important to "fit".

 

I had these on mine but got rid of them because the tire kept on rubbing on the quarter. rear were 15x8.5 don't know the backspacing with 255/50r15 and front with 14x8 with 195/70r14. Oh, had some air shocks on there too.

 

15x7 front and 15x8 back
