It was nice in this part of Pennsylvania too, able to repair sils and doors today with the weather being just right for it! He probably does understand, it's as obvious as it could be what parts are going to interfere, just try to put it together! Lol I wouldn't stress too much, I used off the shelf washers that weren't exactly identical as real shims would be, but the world of modern technology gets them pretty damn close, anyway they worked just fine, I did use calipers and act selectively with quick measurements and just made sure I stacked each with the stamped side down and it made a really straight disk, and that disk served as my front brake with zero failure and a few accidental lock ups, again no failure. That was just to get the (large bb5 and 7) caliper away from the spokes, simple logic says the original caliper is a lot smaller than the ones I had upgraded through.
Smaller calipers exist, I know I have one right now amongst the other oddball parts, actually it's still in the plastic bag it came with. It's a mongoose terrex stock caliper. I'd send it to you but you should know it's a pretty low quality part, and the replacement pads don't exist from searching, but you can order them from mongoose. I had one spring out of the ramp while trying to adjust one, and as the pull gets shorter because you can't adjust pad depth the brakes don't work as good and then suddenly pop out and rolls the bearings into the next ramp ahead internally, then the brakes get loose as f**k and with the levered double brake lever the new slack in the one cable makes the other brake pull very lightly and so you suddenly have almost no brakes.
You still want it it's free? If you have the other type of brake lever you can use it safely since if it pops the cable slack doesn't affect the other cable.
