Here's the bottom line, I want to convert my car from manual steering to a quick ration power steering box. From what I've read on this site and others is that the 3rd gen Iroc camaros have a pretty good box for this, at a much cheaper price then like an AGR box. But they have metric fittings. I've also seen some cars have braided power steering lines using fittings like Aeroquip. Does Aeroquip make metric fitting so I can go strait from the box to the pump? Also what pump will work on this box and still bolt up to a factory style bracket on my big block? If I buy a factory pump made for a 68 camaro, will it work with the newstyle box? I know this is alot of questions, and I appreciate all answers. Thanks, Mark

If you want a stock type pump mounting. Buy repro brackets and a repro pump pulley and use a rebuilt pump with a bolt on pulley, not the press on later style.
The later style has a larger shaft and repro pulleys won't fit them.

On the box, you can use adaptors, or Lee sells a seat that can be pressed into the box, and the threads are close enough that the US holse will fit the metric threads.

I'm sure there are aeroquip fittings for PS, and Aeroquip sells a blue hose to use for PS applications.
Aeroquip hose MAY be slightly noiser in operation than stock hose. Just something I've read, not experienced.
Lee sells a steering coupler to fit the smaller shaft on the later PS boxes too.

I've got some steering swap info on my suspension page below.

Mark, I got mine from Speedway b/c the price was right along w/ no core charge. They are rebuilt by a nationally known company!

I think you need the little one.

I bought my pump brackets from Allen Grove b/c of the hassle of finding all the NOS stock stuff. Allen Grove also sells the crank P/S pulley if you want it. I'm not running A/C, so don't have that hassle.

I just went to the bone-yard and got a good used pump pulley for $10 if I remember right. I will check pulley alignment when I get my engine in my car. pdq67

Paul, you need to get that car done so we know everything works, then I can do the same stuff, hehe. I actually have a nice March aluminum bracket and pully for a pump. I was wondering if maybe a stock pump wouldn't pump enough pressure to work with the faster ratio box, or something like that, I really don't know much about the stuff. I think I'll call speedway and see what they have to say. You can't beat that price on the box.

Just be aware, I don't think those boxes are not the fastest ratio.
I think a fast ratio would be 2.5 turns lock to lock.
Great price though!

Hi all. My power steering box was very sloppy in my 69 Z. I have a friend that has a zillion T/A's and he gave me a power unit (2.5 turns) from a 1980 WS6 T/A (metric lines) to use while I get mine rebuilt. I think 1980 was the first year for metric fittings. After a little research I contacted Lee Manufacturing Co.-toll free 888-698-6697 and they sent me the seats/inserts- #40620 Pressure Seat $3.85 and #40630 Return Seat $3.85. Easy installation. Just look for the pump and brackets particular to your car/engine combo. The early hoses will screw right into the metric power unit perfectly. My car has a very solid and firm steer with plenty of control. I may just keep it that way.

Good Luck.

Gary:

A friend of mine has a 78 Hurst Firebird, its a parts car(400+4spd), do you know what a ratio this would have?

Sorry to go off topic.

Hello Team Canada...I'll do a little research on this and get back to you.

Check out this website. http://www.iwaynet.com/~gl&lisk/1978ta.html


Everyone I talked with into the Firebirds say there is no such car and that GM was using two types of t-top hatches, one of which is made by Hurst. The info on the website indicates that the power steering box went from 16:1 to 14:1 ratio.


I hope this helps.


Gary
