There you go
Edit: I would get a better set of front disc brakes, and just re-build the rear drum brakes.
The rear is only roughly 25% of your stopping anyway, that's a cheaper route.
I boguht a set of willwood front disc brakes from summitracing.com.
Completely worth it.
I was looking at rear disc brakes, and there aren't much for rears for these cars, the best disc brake kit you will find is what they basically use on stock Si's or SiR's.
