[H20911]

Well.....I should have stayed with the buy the complete kit theory as far as the brakes are concerned but I bought some calipers a while ago and would like to use them.

I have a 77 911s and the parts that I have are:

4 calipers (the set) from a 96 993 (they are factory black)
2 adapters that mount the new front calipers to the spindal
2 front 89 turbo rotors.

what I think that i still need is the the rear rotors, a new master cylinder, a way to mount the rear calipers, and the hardware to mount the calipers to the adapters and spindals.

the questions are where can I get 12X1.50X70MM bolts in internal hex head ......and what is this mercedes master cylinder that I am hearing about and does anyone have a part number for it? the hardware search is diving me a little nuts.
