Also I see on other posts the original wheels were 14 inch. 14 x 7 with Redlines? T.A.? I am quite confused about tire size/selection front/rear. Any help greatly appreciated. Rubber spring inserts vs spacers? Detroit Eaton springs? I have tried to stay as original as possible.

 

Your car originally came with 7.75 x 14 tires. 195/83 x 14 or a 205/70 x 14 would be todays equivalent.
14 x6 were the original wheel sizes. 15” wheels and tires first became an option in 1970.
the rear coil springs utilized a thin rubber spacer at the top of the spring for noise control.

Thanks for your help. Same size front and rear? Thoughts on lift the rear 1 - 1.5 inches?

 

Ames has Ralley I wheels in different sizes and as a complete package of 4

 

Thanks for your help. So what Redlines came from the factory? I see Coker has US Royal, Firestones, and Goodrich. Any way to tell? Suggestions? I plan to use Rally I wheels, 14 x 6. Thanks

 

Redlines were standard on the GTO through 68. Whitewalls were a no cost option.
