![]() Hey everyone,
A friend of mine told me that the Ford 9" in my 1970 Mach 1 is either a 14 spline or a twenty spline. He said that with the motor I am putting in it, I will rip it apart (I am putting in a custom built 514 Stroker CJ with approx 950 hp). Is my rear end really only a 14 or 20, and if it is, should I change it to a 37-spline? |
