Brake Conversion

The factory never installed them on the line in 65 (that started in 66) that is correct. They came in the trunk of the cars that were supposed to get the disk's as a late year option, dealer installed like the A/C and stripe IIRC, as well as other optionals that were introduced mid year. Although Chrysler engineered the 'upgrade' with factory K/H sourced pieces and part numbers, the single pot M/C was just retrofitted with an extension to provide the 8 disk pistons with enough fluid. It was an option, with Mopar part numbers and it was engineered with the donut reservoir for the single pot M/C. Now that is the first thing I say to replace as it is a dangerous (ie, no redundency) system. Easy enough to use a 67 disk/drum M/C as it bolts right in to same bolt pattern. The 66 FSM and a 65 addendum address the 'new' disk brake options for that model as they were available in 66 off the line with disc brakes.
