To simplify things and keeping out of the rabbit hole of headaches, my recommendation would be to send the whole entire original p/s to Dan Chock for a rebuild.
Dan is the Ford p/s guru and is renowned for in the classic Mustang world for his attention to detail and quality of his rebuilds.
He is very personable and will take the time to talk to you about your needs.

He has o/e ps now , there are parts down stream in the Borgeson set up that have to converted to manual configuration, Pitman arm included ,  which leads to more cost and complications.
It depends on the individuals skill levels on how much he wants to get involved.
If you want to get down to the nitty-gritty the EPAS out shines both no pump, no oil - no hoses, less under hood temps. etc.
Pick whatever spins your crank.😁

Yes, to each his own, but consider this: I've had a rebuilt '67 Ford PS pump, a control valve, and all the parts to convert my '67 from manual to power sitting on a shelf in my shop since about 1994.  My '67 has a Borgesson system in it.  If you're wondering why I would spend money on something I in essence already had; its pretty simple.  I drove a car that had factory PS and hated it so much that I decided I would simply live with the manual steering, and never installed the factory stuff.  20 years later when I decided to do some updates to the car the Borgesson was available.  Not at all sorry about that swap.  Maybe one day the Smithsonian will want that factory setup, because that's where it belongs IMO, next to the steam engine and the cotton gin. 

It's looking like the Saginaw pump may not be an option after all.  The AC compressor sits directly above the PS pump and there doesn't appear to be enough room for it.  Even if it can squeeze in the space in place of the factory unit, the top cap would be practically impossible to get to once installed.

I can see what you are saying MS, and also that cgomate's situation has the AC compressor in the way. That bracket of yours would definitely add stability to the installation. Guess I'm lucky that mine hasn't failed yet.

Bracket looks good to me.  I think I'll do this in stages... I'm going to get the Borgeson "Upgrade" kit that uses the ford factory pump. Mine seems to be working properly (quiet and not leaking) so we'll see how it goes.

I'm still learning this car's quirks & personality.  If the factory pump becomes an issue, I'll upgrade it later.

Ron, some people may just be luckier than others on the bracket.  Mine failed.  There are a bunch of posts about failures on various forums.  Having messed with accessory drives on various makes and models over the years I can tell you no factory mounting system is anywhere near the way Borgesson mounts that pump, basically relying on bolts and spacers, which can flex with no triangulation.  Overall they build a great system, but the pump bracket and lower column bearing leave a lot to be desired. 
 

Like Ron, I’ve had my Borgeson pump installed since 2011 and haven’t had any issues.  I do understand the two-point vs. three-point mounting arrangement discussion and agree a three-point system would be ‘better’.  I’m going to pay closer attention to my setup in the future.

I am wondering about the bolt breakage issue and if what I did made a difference. The two spacers supplied with my kit from Borgeson were 2" and 1/2". I needed 3" of spacing for my pump to line up with my lower pulley. I had some 1" steel stock that I gave to a machinist at work to make me two 3" spacers. Since the supplied bolts were too short for a 3" spacer installation, I went to the local Ace Hardware store and bought two longer grade 8 bolts to install. Maybe the higher strength bolts make a difference.  I did have to make one modification after the initial install. At higher rpms, the belt would contact the water pump pulley, so I elongated the mounting holes to move the pump so that the belt would clear the pulley.

Another thing worth noting is that I found the amount of assist the pump was set at the factory to provide to be excessive and made the handling twitchy.  I greatly reduced the assist with the kit from Borgesson.  I've wondered if that in any way adversely affected the pump load on the belt, causing more flex and eventual failure.  BUT, I still stand by a two point mount being Mickey Mouse.  On a Chevy you would loose one point of mounting if you installed headers (they loved to hang stuff off the exhaust manifold studs), and I would always engineer a replacement for that 3rd point.  Never had single issue.

I think Don is running his original Ford pump on his 66 GT with Borgeson box.  Maybe he will see this post and respond

As I installed a Vintage A/C system a few years ago, the mounting for the PS pump was changed, and is now a three-point support, very solid.
