Need advice on how to put new brake boot in

[GOPAPA]

I am putting in a new brake boot and want ideas how to do it.. without taking to much apart..

I have pictures here to help you point out and explain to me just how to do so.. and also can you tell me where I can buy a new bolt that the brake peddle pivots on.? I assume it's a bolt with a collar on it so the nut will tighten only to the collar and not stop the peddle from being free swinging..

thx gopapa Larry
