70 Formula 535

[Alponcho]

I understand that DSE recommends 5.5" back space for the rear wheels, but I decided to double check with the Wheel Works tool I borrowed from MCB. It looks to me like 5.75 might work a little better with respect to the quarter lip. But wondering if I'm too close to rubbing anywhere on the inside? Worst case is that I'll need .25" spacers. Thoughts?
