1966 Disc Brake Conversion Questions
see the following location for a full summary of the available wheels & which models featured the 14 x 5.5 wide rims that are needed for the Scarebird installation:

Yes the 14 inch ralleyes are 5.5 wide & explain why those who used the ralleyes didn't come across the wheel rubbing on the caliper problem.
You don't need ralleyes to get 5.5 wide......5.5 wide regular wheels were used on some models in the 70's ...but not all!!!
Just make sure whatever wheels you use have the correct inside diameter and rest on the hub......not on the wheel lugs!!
I've done two installations of the Scarebird package and the ease of installing plus finding reasonably priced replacement parts at you local NAPA or whatever look like positives.....There is about 25k on each of the installations with no problems or replacement parts needed yet.
ps: you might find replacement 15/16 inch dia bore dual master cylinder that came on a 72 Demon with drum/disc comb to work nicely without a porportioning valve.....did for me on my 65 Darts.
