Hey guys, hopefully I can get some help on this. I have a Chassisworks rack and pinion that calls for optimal power steering flow rate of 1-1.5gpm. Which power steering pump has that flow rate that I can bolt up to an LSA out of a ZL1. Also their power rack and pinion has an output shaft of 16.8mm DD. Anyone know where I can buy these size u joints without spending $100 per u joint? Here is the link to the rack:

Any help is greatly appreciated
