Mustang 2 Power Steering

[Wannabebad]

Hello,

We are worn out from trying to move the truck around some today as its nearing being road worthy. The problem is the manual rack it SUCKS when your moving in tight quarters. We havent the slightest idea what all we need to convert to a power steering setup. Can someone tell me or point me in a direction that will show me all I need? I have done some searching on here and have read some about the GM pumps putting out too high psi for the mustang rack causing twitchy steering. If you could list what I need (complete) and a source for parts.

48 Chevy w/must 2 and a 350...
