Air shock options

I Brought the rear end back to A body specs. It was a wider B body so that will help. Wheelwell openings are actually only 12.25 though so I'm likely changing tires. Can't have 1/8 inch clearance on either side. Wheels and tires are a whole 'nother issue. Really am leaning to original Rallye design as of now but probably a wider than stock rear wheel.
