Re: Jeep box upgrade-PICS-and then some...

Could someone please post a part number for this box. The boxes are different with different engine sizes. Or do you know which engine size you used when ordering steering box. Thx.

Re: Jeep box upgrade-PICS-and then some...

Thx for the response but the guy at the O'reillys counter only knows how to find parts by make,model,year, and motor. Is this steering box any smaller than my original 72 box? Thanks again for your help.

I think I may do this, as my hoses are nasty and dont route where I would like them to.

Re: Jeep box upgrade-PICS-and then some...

While I was pulling the steering box of the jeep today, I noticed the power steering pump looked like a lsx pump. All I needed to do was pull the pulley off and reinstall it backwards,and it fit into the ATI Procharger power steering relocator kit. $80 bucks at the local LKQ was all it took to get back on track with my Procharged LQ4 72 chevelle project. Thanks Guys!

Re: Jeep box upgrade-PICS-and then some...

I did the swap today using a 1998 JGC box rebuilt from autozoneEverything hooked up fine except I am having a n issue with the pitman arm.It appears that the shaft on the JGC box is smaller than the inside diameter of the original 1967 Chevelle pitman arm and it is a very sloppy fit.I do not beleive that my arm is gonna work with this box,because it will not spline up properly.Has anybody seen this before and if so what was the remedy.Im stuck until I get an answer.I was using a 1998 JGC Box,Lees line adapters and original PS hoses from remote resovoir.Help me out guys

Re: Jeep box upgrade-PICS-and then some...

Did this swap over the weekend using a junkyard jeep box and the $10 advance rag joint.

The difference is AWESOME. Excellent road feel, no slop, and the quick ratio is an excellent bonus. Mine is barely over 2 turns lock to lock (might be limited a hair due to oil pan/tie rod clearances).

I now just need to find a pressure line that has a straight 2" o-ring joint on the pump side (99 corvette PS pump, curved lines won't work) and jeep fitting on the box side. Right now I'm using a compression fitting like I was on my stock box to join 2 different lines on the hardline section right before the box.

Re: Jeep box upgrade-PICS-and then some...

I've been wanting to do this swap for awhile but I don't have any power steering equipment whatsoever. Mine's a 66 with a big block but doesn't have a power steering pump or anything. I've read that the reservoir needs to be mounted externally, on the radiator support I think, for this to work due to space limitations. Does anyone know what else I would need, or more accurately, what part numbers or where to get them for this setup? Thanks for any info anyone can provide.

This is one way to do it:

http://www.chevelle.com/1965-1968-BB...P5139C643.aspx

or find a used setup on eBay/Craigslist/etc. You'd need a power steering box, of course ...

Re: Jeep box upgrade-PICS-and then some...

Recently, I read an article on the Jeep swap-over and it mentioned that you have to change the pressure valve in the stock GM PS pump to the higher pressure valve. However, I don't remember ever reading that in any of the forums. Can someone shine a light on this for me? When you swap over to the Jeep box and you use the original PS pump, did anyone change the pressure valve in the pump to the higher pressure valve? Or, did the stock pump work OK with just the hose change-over? Thanks!

The pressure valve is set to 950psi in pre-1970 cars, 1450psi in '70 and up, according to Jim Shea. If you've got a '70 or later car, you're fine, if not, you've got to take the pressure valve from the donor car, which is the fitting the pressure hose threads into on the back of the pump - it just unscrews. As an added bonus, a later pressure valve will have the later O-ring seal, but the pump end will be the same and will thread into your existing pump.
