Can't get a bigger rotor... they don't make a bracket for non-disc frames that support larger rotors that I'm able to find. I can only find 3 brackets... 1 is a death trap... nix that one. The other two use 160mm rotors.
EDIT: Or is it just the POST that is bigger? Do I need to find a rotor that supports 203 mm or just a post? Sorry guys... this is all brand new to me.
You have to size the mount to the caliper. Measure center to center on the caliper bolt holes and size a correct mount to it.
eBay has a bunch of thst stuff.
Did you use the 160mm, 180mm, or the 203mm for the rear disk...Caliper room is THE reason most everyone uses the 203mm disk size in the rear as I have.
The first two pics shows a more close up look of the size, spacing, and comparison of disk versus sprocket size and caliper postioning the third pic shows front and rear pic size differences between the two disks...Most people miss this important difference when doing disk brakes.

In your picture you have the sprocket outside of the disc. ???
To spread your chain stays, install the althread and turn the nuts out until the desired width in attained, put an extra nut on the outside of the althread to keep it in place. Get a spreader bar clamp and spread the inner part of the stay.
