I just got my a$$ kicked by my Contour. I've been working on a rear subframe/BAT swaybar/rear drum-to-disc conversion.
The rear rotors that I bought don't fit on the hubs!! WTF?!? I thought that all rear discs were the same? I checked BAT and they only have one part number for ALL rear discs.
I have a '96 GL with stock rear drums with ABS. I'm doing the swap using '98 E0 SVT parts. I don't have a set of calipers that open up wide enough, but I'd guess that the hub is a good 1/8 to 3/16" larger than the inner diameter of the rotor.

I apologize if this has been covered before but I'm too friggin' tired to search.

Thanks,
BP
