WTF Front Brakes?!?
I run the pin-type calipers on my '68. Used '73+ spindles and UCA. Found brackets from '78 Cordoba with 11.81" rotors, same as police car rotors. Much better than the 10.25" rotors, but the same calipers. The only difference between the pin type and sliding calipers is the bracket. I like the pin type as the slider type can wear the slide leading to pads sticking. In modern brakes, they use a SS wear pad that gets replaced with the pads eliminating bracket wear. These are the best brakes I have ever had on my Cuda. Started life with K-H 4-piston disk brakes which were good, but not up to the capabilities of the much larger police brakes.
To mount the calipers forward, I had to use the bent swaybar, which worked fine.
