Installed a mini starter, had to add a couple of extra shims. I was reading the forum comments on the saginaw pump and ford mustang rack pressure problem. One guy said to get a Borgeson pump #800312 and end the problem. I did, cost a bunch, also got their bracket for SBC and line kit. A very good installation. ALSO GOT A NEW MASTER CYLINDER and proportioning valve for ford brakes disc/disc.
