I ride a 69 Chrysler 300 and after a small crah I rebuild the whole front end and parts of the rear end.
All parts for the front end I bought at FirmFeel. Biggest sway bar with 1.25" - massive!
HD strud rods
PU all around and their tubular UCAs. KYB shocks in the front. Rancho 9000XL in the rear.
I also installed FF rear swaybar. Steering is with a 20:1 manual box.
The difference in comparisson to the original set up is like day and night.
Brakes are SSBC Force 10 with 4 pistons. With yellow EBC pads, a 15/16" MC, residual valves
and distributor block to reduce the back stopping power (ori drums) to a minimum,
the car stops great and I can get the front brakes to block completely.
Due to my TTI headers I am stucked with my original 0,98" t-bars. Announced that already
to TTI and they wrote they might take it into their buildings - we will see.
Wilwood now also offers disc brake kits for c-bodies.
Still on 15" wheels. But when ever I reached my goals to drive a 11.99 or less,
I will switch to a GV, 17" wheels and big brakes with hydroboost system and borgeson steering.
