I bought a 1970 Fastback and have to do some front end work on the car and cant figure out which brakes this car has.
Can any one help with the numbers given off the spindles and or the calipers?Spindles: C7SA 12" rotors
3107B
20 Caliperes: 8W20
71304 Yes these have heavy duty 4 piston calipers! [This message has been edited by BobbyR (edited 08-27-2002).]

Does it have heavy and large 4-piston calipers?
Maybe it has the "Trans Am" brake kit that for sold over the counter in the early '70s.

I do not think these are from a Trans Am because there is a Ford stamp on the spindles but thanks for the info.

The "trans-am" he was referring to was not the pontiac car, but the race series, and more specificly, the parts sold over the Ford dealer's counter (Muscle Parts). I believe it was part of the Boss 302 stage 3 suspension package or something like that. I'll have to check the manual I have on that.

Could it be that someone has swapped '67 style big car (Galaxie/Thunderbied) disc brake spindles onto this car?Tracy

That is exactly what I have on my car. With all my new parts (stock)...i.e. controll arms, tie rod ends, ball joints, those spindles do not fit. I understand the Granada and Versailles parts fit. Do you know what year and model, spindles and brakes, fit on a 1970 Mustang?[This message has been edited by BobbyR (edited 08-28-2002).]

The "Trans Am" is the race series.
Ford actively raced '69 and '70 Boss 302 mustangs in the Trans Am series.
There was a brake system that was offered over the counter for road racing.
This kit used a mixture of Ford Big car components. Your setup initially sounded like this kit.
BTW, can't you use T-bird Tie rod ends?
Do you think the lower arm you have is from a T-bird?------------------

Trans Am was a racing series and if a car wanted to run special parts, they had to be over the counter parts, I believe.

I checked with my local parts store for the controll arms and tie rod ends on a 67 T-Bird and those are special order, around 100.00 for all four. Would it be smarter to try to get this thing back to stock (not for financial but for correct steering geometry)

I see no problem as long as the alignment can be correctly adjusted with the T-bird parts.
