WTB ST-300 Kit?

My friend is looking for a trans rebuilt kit for his `66 GS,where can he purchase a kit from?

Thanks

 

I know that Poston Buick has a kit for about $180.00, and TA might also have one. Another place you might try is Kanter Auto. They sell a lot of parts for antique and muscle cars.

 

I did a search and found the kit from Fatsco and another supplier in the 130 to 140 range. Seemed very reasonable. and way easier than I thought to find.
