Thread: Model A Donors

Tweet

Ok weather is getting close to breaking. I'm putting this A together with all ford parts if i can . The following i would like to ole skool from donor's . I need some experience on Model A to help take some guess work out of it . To refresh i have a 1984 5.0 and a 90 GT T-5 trans with a 1970 cougar 9 inch. Brake and clutch pedals from a 67 Mustang .

Question #1 is what Ford Model car would be the best Master cylinder donor for a firewall mount . Will there be a specific size i should be looking for. I will be running Disc/Disc on it . I may also go with the power but not yet sure on the clearence to engine the booster may present or what diameter if i do add one. Ive seen the one's for sale but chioce is a donor. I did some reading on pedal ratio so i dont for see a problem on any choice . Maybe a complete set from a Mustang with brake and clutch pedals .

Question #2 steering columns. I have also read that some have been using the FWD version because of it's shorter length in the tube . Heard these are in the low 23inch to 25 inch range. This brings the steering rod out at angle in the firewall before the exhaust becomes a issue ?

Question #3 has anyone used the original ford shorties that came with the 5.0 . I did a hold and fit and it looks like the collector angles down at the right point near the firewall . I'm not really sure on this one though.

Not sure how much help this will be, Bob, but for comparison purposes... In my coupe I have a Maverick 8" rear with the stock Ford drums and mid-70's AMC disc brakes up front. I am using the master cylinder from a 1985 Mustang and the brake pedal from a '95 Cougar. Although the master cylinder originally came from a car that had power brakes, I am using it without the power booster. It is small enough that it mounts on the firewall without interfering with any other components. (If you look in my gallery there are several pics that show it.) Required pedal pressure is not excessive. If you've ever driven an older Mustang or Ford Falcon without power brakes, that's about what the pedal feels like.

Thank You J . i was wondering if the mustang was small enough . I was also thinking that the pedal assy. and clutch cables would be right length to install the 5 spd also. I seen a 95 pedal assy in someones pics and bracket looked fairly compact .
