Yes they were. The fronts are the standard 105’s and the rear are 205’s. The cheaper 105 have a standard backspacing and are a 1 piece wheel while the 205’s are 2 piece abs can be ordered in a custom backspacing. They took about 3 months to come in. Also they stress not exactly identical but you have to look closer to tell the difference. One has a chrome outer ring and the other is polished.

Quite the up charge on custom orders! Geeesh
 
I am embarrassed to say that ive spent more time researching wheels than i have on my wife's engagement ring.

After months of back and forth Ive settled on 17's!

I picked up American Racing VN215's--17x8 +8mm, rears and 17x7 0mm, fronts.

Tire choice is the next big obstacle! The Nitto NT555 G2 appear to be the overall winner, but i cannot decide size.

Looking for some advice. Hoping for as much aspect ratio as possible so to not look like rubber bands.
 
I ended up with Continental extreme contact sport 02. I won't be driving my car in snow and they supposedly have decent grip in wet weather. I don't have an close up pic of them but as far as tires go, they look good. Only drive with them for a few miles since they were out on, but handle very well and no road noise.
 
Very nice! Congrats!

The Firehawks handle well and are quiet enough, not that I can hear road noise over the exhaust. ;-D

Well, I have just ordered chrome-plated 15x10 rally 2s for the rear of my '69. I have a set of new springs for all four corners with a 1-inch lift. I plan on the 255s. The guy who had it before me had 275s on it, but it looked like the tire was going to pop off. 15x8s
