The pre 73 Ford trucks have drums all the way around and maybe 73 and 74 4X4s,I think there is a aftermarket Corvette master cylinder that has the brake line ports on either side but I decided on the Ford master cylinder due to availability at any parts store and lower price. I got some 1/8 thick metal and made a bracket to adapt the master cylinder to the 37 pedal mount and I had to cut off where it bolted to the original trans and then made a bracket to go from one of the original master cylinder mounting holes to a bolt on the tailshaft of the T-5 to keep it from flexing
