The 4 speed GSX disc brake pedal foot pad is not the same as a 70 GSX with an automatic transmission.
Actually, it is 7 out of 10 for an auto and 3 out of 10 odds for a 4 speed. Do not accept the repro auto pedal. They did a terrible job. I gave several of the factory pads to JW a long time ago. He may still have some. Check with him.
There are no known exact repop's of the original that I'm aware of. I will hold out for an original. The resto shop misplaced my original. Thanks
