Question: Are the pin-type calipers from the OP's 71 properly dimensioned to mount onto the brackets for the 11.75" rotors?

I have a '72 pin type disc setup on my Challenger, along with the later large-bearing-spindle (73-up) sitting aside now (thank you 71hemigtx), so, I believe the OP and myself are in the same situation. I want the 11.75 discs but would prefer the pin-type calipers instead of the slider-type calipers. Can the 71/72 pin type calipers be used with the larger 11.75 discs?... with the proper bracket?

I've considered the Viper front setup and recently tried various rims on that setup (thanks again to Sublime 70 Charger!)... too tight for my rims and will NOT fit with factory steel Mopar ralley rims!
