My everlasting thanks to Mike Pittinaro for the info on the Supra rotor conversion. Now I just need to find out where to get new pads. Someone has mentioned NAPA but my local NAPA pleads Ignorance. Regarding wheel interchange, I have some information to share for what it's worth. 1. For the 67-70 models (5 on 5") GM light truck 2whd wheels are a ggod fit and are available in both 7" and 8" widths. These only require the switch to 13/16" lug nuts and the wheels are usually zero offset. With wheel covers on , no one will know you have cheapened your Imperial with GM wheels. 2. For the pre67s, a 5 on 5 1/2" pattern is used and although this was the pattern for ford 1/2 ton trucks, vans and Bronchos, beware! The early wheels were not designed for disc brake caliper clearance. In my personal experience the best of these are the Ford supplied 15 x 7" that were on many Bronchos and F150s. These can be identified by the rather standard size hub hole, as opposed to the generic 5 on 5 1/2" (15 x 7 or 15 x 8") which has a very large hub hole to fit Jeep and Scout front hubs. This is one area where the famous Mopar interchangeability can be a problem IE. the Dodge light truck wheels (for some recent years) will physically fit, but the offset can be a problem (as I recall it is too much positive offset) 3. Someone questioned the need of wider than 6" wheels for my 69 LeBaron. Well, I can't speak for the tire industry, but I'm firmly convinced from years of Mopar experience that a 235/75 R 15 tire on a 6" is not an optium situation and that handling and tire mileage can be improved with a slightly wider rim. 4. Not being very familiar with 1953 and earlier Imperials I'm curious hhow one gets by the problem of Mopar wheels of that vintage not being designed for tubless tites. Enough already...
