Topic: Power brake and power steering conversion for a 1966 Mustang

[Casey R.]

I'm using a 1970 spindle to convert my drums to discs.  Will the power steering gear box and other items from a 1968 coupe work on a 1966 fastback?
Thanks,

That will depend on a lot of other parts that you will need to have to convert to a disk brake setup.  So, what other parts do you have besides the '70 spindle?

The gear box is not compatible with 1966 (64 and 65 included) cars. You need a 64-66 box. Typically, a 70 disc brake setup also used power assist and with power, the brake pedals on a 70 (67 to 70 included) drum and disc systems are different. Big problem. You got a proportioning valve?

This reply probably comes too late, but I wanted to point out that the '68 Mustang gear box IS compatible in a 1965-66 Mustang.  All you have to do is add a rag joint.  The best way to do this is to install a 1968 steering column which has the added safety advantage of being collapsible.  I have pictures of this installation if you are interested.  I don't believe power brakes are necessary.  I have converted to '68 Mustang single piston disc on my 1966 Mustang and the manual foot pressure needed is very easy to apply.
