disk brake kit

I too am considering a disk brake upgrade with a SBP to 14" stock wheels, so I'm watching replies. I've heard of this issue before. Some companies have published a section drawing with dimensions so you can have an idea if it will fit. That's pretty good.

People tell me that I'm full of s............uggestions, so this is what I think should be done. You pay shipping + a $25 deposit, and the brake manufacturer sends you an accurate plastic mockup of their rotor, hub and caliper. It arrives in 3 days and you can see if your wheels will fit with their brakes. You send it back and they refund your deposit. This very simple "fit" test takes very little time, but it could save a lot of "hard feelings."

Well, brake manufacturers?
