That would be great. A good start would be to find out some more PS pump pressures specs for the various combos. These would provide a good reference that covers most of us. If you crack this, you are going to find the smae pumps were usued for many applications. There aren't 11,000 different pump pressures to contend with for Ford or GM pump.

On the PS pump end

1. Late 70s to early 80s fullsize Ford ie LTD with 302/351. (fenders)

2. Late eighties to early 90s Mustangs with 5.0 (others members)

3. Late 70s GM midsize (Camaro, Nova etc) (Vern donor??)

On the steering box end,

1. A 76-80 Volare, 80 Cordoba and an 87 Fifth Ave for example. All these boxes look identical. We are assuming they require the same pressure.

2. Also a 76 Cordoba to see if it is the same for the Gibbon's guys.

Vern,

Your no-problem approach is going to be to adapt the Mopar pump. I know the GM has pretty high pressure. Perhaps Dick can help us figure out just how high.

Thank you,

I see you're getting a rush on research requests. Just keep in mind who's probably smoking PS parts right now. We're dying out here man. Also, have you ever noticed how smart alecky RMF types "Penn Dick" when he addresses you? I don't like the way he treats you. I'd do him last.

 

Anybody know what size fittings I'll need for a Ford '71 LTD steering pump to mate to an '80 Volare Box? Are there any hoses already made up that will fit?

 

I found it quite easy to adapt the Mopar (87 5th Avenue) PS pump to my non-Ford engine. I would think it would be better moving in that direction rather than trying to use mismatched components. I have no idea on the Ford PS pump fittings. You will probable have to have one custom made. I am able to use the stock Mopar hose on my truck.

Another you might include in the research is:

78 Volare steering box
84 Bronco PS pump

I just installed the new pump since I changed all the brackets to add AC. Haven't driven it yet so I'm very interested in your research in case I have made a mistake.
Thanks.

 

On the Mopar boxes, the cop cars came with coolers and fast ratio steering. The FRS box is a much firmer feel to it as well.

As we are putting out combos I would like to find a Ford PS pump to use with a GM box.

 

Dewayne, I think you read my mind. I've been thinking about that old thread a lot lately also. I have a Ford Granada PS pump (late 80s) and a 78 Dodge Aspen steering box. It is way easy to steer and a maybe a little too sensitive. (It cries if I call it a name) But seriously, I hope this thread can produce a good resolve. Penn Dick, if you could please include mine in your long list I would certainly appreciate it. Thanks, John

 

That mushiness is the box, not the pump. All Mopar PS boxes from the 60s to early 80's feel like that. In the Mopar world you upgrade to a 85ish cop car unit to firm it up(or Firmfeel aftermarket unit) and/or get a longer pitman arm(which is hard to find).

 

Perhaps to a degree they are soft steering. But old stock Mopars steer no where near as easy as my Volare/F100 does with a little too much pump pressure.
