I'm looking to upgrade my 1968 Coupe 350 to front power disc brakes. I would prefer to get a full blown kit with everything from brakes, spindles, master cylinder, etc...I'm seeing a lot of options out there. I see some kits on Firebird Central in the $600 range and some up in the $1200 range and a couple in between. Not using on track or racing just a little fun driving around town. Thanks...
