I'm looking to do a borgeson steering box swap on my 68 xr7. I'm trying to save a few bucks and possibly buy the pump from somewhere else for a little cheaper. Does anyone have a part number that is the correct pump for completing this swap? I've read that this is a common pump for GM vehicles; but haven't found a part number or what exactly it comes off of. One other concern is that the box I believe is suppose to have about 1000 psi; just making sure this information is correct and that this pump matches.
