Barracuda and chrome reverse?

Just couple weeks ago I bought a set of chrome reverse for my 67 barracuda (rear wheels 15x7) primarily for the custom backspacing - 4-5/8" when I picked them up the guy had them on 68 barracuda with a 67 B body 8-3/4 rear end. Exact combination I had - what are the chances of that.

Fit perfect I had 225/70/15 tires mounted as that is what I had. Can go wider and will keep my eyes open but on budget so these will have to do for now.

Have same size tire on front with torque thrust rimes and 3" backspacing. May have interference once I put my engine in. Am planing to have to go to 205/60 or something of that nature. I will wait until complete so that I do not buy too many wheels and tires. I will keep my eye out for chrome reverse for front also.
Like the looks so far.
