Replacing SBP Rotors

Oh crap! I work in Renton! Wish i'd known, I might have used them. Oh well, I really am impressed with what I got from calipersonline. Oh - be sure to insure those cores with UPS or whoever you use to ship them, it's cheap and that way if they lose them you're not out your cores. thanks for the pics of your setup. By the way I can't remember if I took the calipers off the front or the back of the rotors (doh!). I see yours are on the back - is that stock for a '72? I thought it was the front but I didn't take pics. Also - seeing your master cylinder made me think of another question. I'd like to reuse my booster that is already on the Scamp and just get a new master cylinder. That will work ok, right?
