Gary, I dont have an answer to your question but I am curious what some of the members will come back with since you indicate you do not want to swap your spindles. Most likely someone will have found a source who made special caliper adapters and related items to make this possible. Otherwise, it may be you would need the parts from a like car that had disk brakes.
Anyway, the reason for reply is I wonder your request is due to the expense for a conversion. I'm sure you realize you will have to change your master cylinder and add a proportioning valve, etc. I spent some time looking for the same for my 68. I eventually gave in and bought a complete disk brake conversion kit from CSRP. It was my second kit and everyhting fit and worked great just like it did for my 66. The kit was complete with EVERYTHING and paid less than $600 for it (including shipping). This makes it about 1/2 the cost of an SSBC kit.
He has 3 basic type swaps
- KH 4-piston
- Granada Swap
- Original OEM Type Swap
Jusat something to consider
