From the e-bay post:
These came reputedly off of a 67 Imperial. I bought them because they were the same rotors (I think) as I had on my 66 Sport Fury with the disc brake option. They are 11 7/8 diameter.One is .865 inches thick one is .845 inches thick. They've been on a shelf in my garage for about 20 years so they have a good surface coat of rust but they are not scraped up.Wouldn't take much to cleam them up.
My 1969 Imperial manual lists specs for 69 Budd rotors as: dia 11.87" to 11.89", thickness 0.8725" to 0.8775"
These appear to be two piece hubs and if they have the 5 x 5" bolt pattern, I would assume that they fit your application. I would verify with the vendor the bolt pattern (5 x 5" and not 5 x 4.5"). I do not know what the min. diameter specs are for thes rotors, but looking at the pictures, I would suspect that you would lose 0.01" to 0.02" per side to get them in working condition.
I just purchased a hub (1 only, $25 + $15 shipping) for my Budd brake 69 LeBaron and am going to investigate the Supra Rotor conversion with it. I figures I could convert this hub and if it worked, great, if not I am only out some money, the car is still driveable. The items you have listed, assuming that the hubs are in good condition, would give you a good opportunity to look at this conversion to your car with no risk to your current vehicle. That is if you are interested in it. I like the idea of getting away from the old rotors all together. Also, expect shipping to be considerable on these items! Good luck.
