My car was originally ordered with the F4 Sport Wheel 15 X 7 option. When the car came into the family those were long gone. It has had 15 X 7 Buick Rallye wheels for the past 20 years. I wanted to see what the Sport Wheels would look like (they weren't very popular in 1970), so I bought a wheel from ss396.com (NSW-157) and a set of trim rings (NTR-157) and found some dog dish caps on eBay. I'm not sure I like the look on a white car, but this car was originally Burnished Saddle, so maybe. I'm not sure how close this setup is to factory, but it seems like a pretty close match. The only difference I could see with the NSW-157 wheel is the backspacing is 5" and the Buick Rallye is 4-3/4".
Beautiful, looks great,F4 /WD1 rare wheel and tire option only available on 1970 and very early 1971 Big Block GS cars.
