Ok ,
master cylinder is the 1 supplied by SSBC with the front brake kit , I am pretty sure it is 1" I ran it with factory booster and now without booster .
Has standard factory pedal ratio .
The caliper is iron and I had to slightly clearance it to run my 10"wide rims , ok with 8's

I did have some spacer plates cut ro replicate the thickness of the drum backing plate to keep offset correct and bearings/seals in correct position . The POL kit and MasterPower kits have this supplied if I understand correctly , but be aware of this .

Andy is correct Cass (DRDiff) does have everything . He like a few others now use a mustang/ford rear caliper and a slightly smaller rotor . Cost of currency conversion plus freight stopped me buying these . Got my kit local unused for $400.00 . Seller showed me they were available , he bought them , on ebay
