I'm 90% sure all olds rallys used the same center and just changed "hoops" to go from 14" to 15".
I know pontiacs are like 13.25" inside hoop diameter where olds and chevs are 12.5.

I have 14's and 15's
Like 81Cutlass said the "centers" are the same size.
Its the reason I kept the 14's Im waiting for him to make me a custom set of wheels!!!!!!

But if you're worried about whether they'll fit a particular application, it then is the hoop and backspacing that will decide what clears and what won't, as in brake calipers, etc. As stated, all the SSII/III wheel centers are the same.
If you're thinking of going with bigger brakes, just set those 14" wheels to the side...not that you probably couldn't make something work, you just need to decide if it's all worth it with 14" wheels.

I put ls1 brakes on the front of my 2+2 and narrowed the wheels so I have 15x4.5 pontiac steel wheels. From there I ran a 1.5" spacer to bump the wheel slightly outside the caliper since on most of your big brakes you have to worry about wheel mount face to wheel center clearance AND rotor diameter. A 15" pontiac ralley actually fits over the ls1 caliper but the wheel center must be moved roughly 1" out which is why I used a 1.5" spacer (and to fit my c5 wheels)
A 15x7 with 4" BS pontiac rally will fit over LS1 brakes on a g body spindle with a 1" spacer to move the wheel out. A 15x8 with 4" would fit with again a 1" spacer and some slight grinding of the caliper cooling fins (half and inch maybe)
Not so much with an olds wheel. I think it dates back to the late 60's when the pontiac ralley was developed GTO's had bigger brakes than even a 442 or Chevelle so Pontiac developed the larger center wheel. (I could be wrong but I read something that GTO's had bigger rotors)

I guess I need to get into the custom ralley wheel widening and narrowing business
I swear I need to clone myself.....
I like the looks of the stock SSIII over everything else. So I was hoping to keep them somehow.
Thanks for the information folks.
