Convert standard manual valve body to reverse - what is needed?

I use my factory console in the 73 dart sport. Works great with reverse manual. I wouldnt use it with a forward manual, too risky.
As far as the PSI, email cope and ask them. I just got the street version and im really happy with it. Anytime you get firmer positive shifts it will cut down on trans wear because there is less clutch slippage. Might be harder on U-Joints though :) She chirps second gear everytime, I love it.
