Power steering pump for new MII

In my purchasing research, I came upon the pressure problem with GM pumps being too high in pressure for the mustang II rack. The fix is a reducing valve for like $30 or a dial pressure one, or a 88ish T-Bird rack. This thread I'm reading is from 2004, that is like 16 years ago. Has this been solved another way? Or same info?
Truthfully, I'd like to keep things Mopar since its a Dodge truck, but whatever I guess. Thanks!

PS pressure reducer

u need to look more into this.. i have seen what i'll call a by pass valve. it connects between the high pressure and return lines. the more u open the valve the lower the pressure is to the sys. so u can adjust it to your feel.

I used the non-sport T'bird rack, cheaper and works just fine. You already have the rack and I assume, Mopar drivetrain so I would look to other solutions. First, does a Mopar pump pump put out the same pressure as a GM? Second, have you thought about putting a Ford pump on? Likely have to make your own brackets but it would be a final solution. I never had much luck with a pressure reducer.

Thanks Tech, for the life of me I don't understand why brackets for Ford pumps to GM motors are not an item.

So a Ford pump will work better? I thought id be going mopar for everything. I guess its because I keep hearing everyone say to keep mopar, which I'm willing, so that it won't be a Frankenstein. But I guess everyone does it? So whats the big deal with people freaking out when someone puts a gm 350 into a dodge/ford etc.? Now I'm confused again. Geez, truthfully, it's been alot of work just researching!!!

Let me see...Ford rack, Ford pump...yup, should work fine. I do not know what the pressure output of a Morpar unit is but if it's close to the the Ford unit then use it. Yes, research will make your head hurt, but if you do enough the correct path will be much easier to spot. Beats not doing enough research and your head AND wallet will hurt!

Duh, I didnt know they actually used a Ford rack in the aftermarket design. I guess that was a rookie moment...

Yes, now I see it. Buuuuut I thought they just used the engineering of a MII, then used a well suited rack and pinion. Didnt cross my mind that the well suited r&p is a MII rack. I guess maybe because people complain about MII and how the original wasn't strong enough. My thoughts were they took the geometry and made it better.
Well this one showed my hotrod age...
Now i need to research Ford pumps. For real, this hole gets deeper the more I know.

Good! I don't have the time to research so let us know what you find. Every tid-bit of info is just another rabbit hole that the curious will jump down and learn where those with vertigo will just accept status-quo. Jump Alice, Jump.

My Pontiac has an original '74 MII front frame/suspension. Builder used a GM P2 style pump which worked fine with the original rack for over 15 years.
It is still working fine with the '88 T-Bird rack. Rack was changed due to tierod slop/wear.
