Tyres.... sorry Tires question

According to your V.I.N., your car is the 5,267th car built for the 1973 model year in Hamtramck Michigan.
A very early August build for the model year.
Also, according to the V.I.N, it is a 318 V8 car so it should have big bolt pattern wheels on it, probably the standard 4 1/2'' wide.
BTW, all A-Bodies from 1973 and up with a V8 and all slant 6 cars with power brakes got the BBP 4 1/2'' center to center wheels with 1/2'' studs and disc brakes on the front standard.
And the rear ends were BBP to match the fronts even if it was a 7 1/4'' rear end.
However, I have seen cars that were changed to SBP 4'' brakes and rear end sometime after they were built, these cars are 50 years old now, so who knows what someone did to them in the past?
Yes, I would try to get 205 70 14s for it.
