I've been changing a few things on my LTD so as to look more like the KZ1000A or the 900's. I can do most of it easy but I got to the rear brake and had some questions. I bought a 18" rear mag wheel to match the front that will replace the 16" LTD wheel. I see that I may need a small spacer on the right side. Also, the LTD rotor doesnt match up to the caliper so what rotor if any will replace the LTD rotor and match up? I can space the rotor too but had rather find one that fits. Thanks for any info.
