can I upgrade my calipers from 4 piston to single on a 1967 chevelle ss 396 convertible and what is involved? thank for any help I'M new to this. graemlins/clonk.gif

Yes - you can put a 69 to 72 Disc brake setup on your car, but if it already has the 4 piston setup why would you want to?

The 67 Calipers and rotors are available but are more expensive, but would probably be cheaper than replacing everything.

I don't know if you need to replace the spindles wiht 69 to 72 ones or if the 67 spindles will work with the newer caliper mounting brackets.
