Sorry guys, I have searched and read every thread. However in order to avoid buying the flexible rag joint from Lee's or GM for $80 I read I can get the junkyard pieces from those later model gm trucks and such. However, I dont have a junkyard near me. I heard the manual steering rag joint for chevelles fits perfect for the 3/4" diameter. Can I just buy one of the manual rag joint couplers and use that instead?

Is it just round 3/4" with splines 360 degrees?

Or is it 3/4" with flats on each side?

I already have the steering box, and I know about the special metric press in fittings to use my old hoses.

Also, Do I really need to increase my pressure relief settings on the pump? This is for a 68 el camino, however i think the power steering pump might be from 74, as that is where the engine is from.

So basically other than the pump/box and the proper rag joint and the press in fittings, do I need anything else? Thanks and Im sorry if I missed it when reading the old threads.

I am quite sure that your Jeep steering gear has a 3/4 diameter input shaft with 30 splines (or serrations) and a machined flat. (With the input shaft exactly on center, the flat should be at 12 o'clock as viewed from the driver seat.)

The manual flexible coupling that is advertized has a 3/4 flange with 36 splines. So it won't fit.

The other flexible coupling should have a 3/4 flange with a flat and 30 splines. So it should fit your gear shaft. The problem is adapting the other end to the steering column. This is a smaller diameter flexible coupling that was used on many GM cars in the 1980s. It is quite a bit smaller than the typical "old style" flex coupling. The column end is also smaller than typical steering column shafts in the mid 60s era. You are going to have to cobble a connection. When I say "cobble" I really mean that you will need to carefully devise a method of connecting the column to the flex coupling because you are steering the car through that connection. Think SAFETY!

I never recommend butt welding parts that you are using to steer your car. It is always best to be able to insert one part into the other, pin them, then tack weld the joint to get rid of rattles. (Also, you don't want to heat up the rubber disc in the flex portion of the coupling.)

So if I buy the correct one from Lees I dont have to weld it right? I may just do that.
