thank you, I I will do that. I appreciate the link.
Here is my 68 running. 15x8 w/ 4.5 bs rear 275/60/15 front 235/60/15.
It's hard to know without being able to measure the black 68. I called the company that sold that black one, and they could tell me everything but the backspacing.

Very Nice looking 68
reminds me of the one my Dad ordered from the Dealership in1967
but he never got it because a Salesman sold it to someone else
before Dad could go to the Dealership to pick it up
So both Wheel/Tire Combos look like they need more BackSpace
tf you have a Stock Width RearEnd of 61"
Check the Room on the REAR between the current Tire's Side Wall at the OUTside/Fender Lip
and the Room between the current Tire's Side Wall at the INside/Frame
Since you already know that the Rear 8" Wide Wheel has a 4.5" BackSpace
there should be more Room on the INside of ??" so a 4.75" to 5" BS on a 8" Wide Wheel should work
to provide more Room on the OUTside/Fender Lip for when you go to Fast around Corners
To me it looks like the Front Wheel/Tire Combo only has a 3.5" to 3.75" BS
and the Tire is really close to the Fender Lip plus might be Rubbing
or very close to Rubbing when you are at Max Turning
Depending on the FRONT Wheel Width you will need either more BS or a Tire with less Height/Diameter
