My copy of Gordon Hopper's book, Model A Ford Restoration Handbook gives detailed info with layouts. This book was written in 1966 and the plan uses a single outlet Master Cylinder. Speedway sells a dual
MC for about $35-40. I got one for my 30 Town Sedan. A word to the wise, when welding the MC mounting plate, don't weld a continous bead vertically on the frame. Someone did on mine and it's not a problem, Yet! However, the frame is weakened at this point. The only kit you'll need is a set of 39-48 backing plates and associated parts. The brake lines and fittings are standard from any AP store, Good luck with it!
