Hey guys, I have a 72 cuda with factory disc brakes. I have an adapter to put the 11.75" rotor on that spindle. Will the Wilwood caliper adapters sold by Mancini bolt onto the spindle I have? Or is there a factory Pin type caliper adapter that will bolt to my spindle and work with the 11.75" rotor? thanks for any input.

Yes and yes.

Where would one find the pin type mount?

I got one from Dr Diff for my 11.75 using that caliper.

Thanks for the help

just get caliper adapter brackets off of a 76-mid 78 B-body (doba, Charger, Magnum) They used the 11.75" rotors and Pin Calipers. I scored a set and did the same swap on my factory disc 71 Challenger. (bearing spacer for the spindle, new 11.75" rotor, caliper adapter, and reused the caliper!)
