Frank,

You want onna my free "pdqCBB" front caliper bracket cardboard templates that mounts a '69 and newer big single piston and a 1/4" wider jaw Van caliper on a 1988 'Vette 13" front rotor using either drum or disc A/F/X forged spindles depending on shims.

Cheapest "CBB" set-up going...

Let me know..

Probably be best to PM me over on Team Camaro b/c I may not check here often enough is all..
