The OER part should be here tomorrow. If it doesn't work, I'll check out those options.

Is it like this? https://www.speedwaymotors.com/Lares...ro,120567.html




I swear the one on my '01 Blazer is exactly like that, too.

If you look at the really huge blow-up of that one, it's made for a shaft with splines and what I would call a flat

Yes, they are calling the relieved area of the splined bore, closest to the underside of the pinch bolt head, as a "flat".
It's a poor use of term, normally when referring to a "flat" in a spline it is a double width spline, with no valley cut between what would normally make the space of 2 splines....like on the output shaft side of the box, so that the pitman arm can only be oriented and slip on the spline in a certain spot.

That "flat" in the steering rag coupler description is just the relieved area of the bore, so that when the bolt is tightened it will pinch tight better than it would if those last 3 or so splines were left in there fully splined.

You'll be good with the OER part, GM didn't make several 3/4"-30 spline couplers with actual orientation flats or anything like that,

That would be something only FORD would be stupid enough to do.

Sweet!

Say, "southwest lower Michigan" sounds like you might not be too far from me. I'm in Kalamazoo. You ever race at Martin?

Many times at Martin, both before it was upgraded and after, but haven't since 2010.

Used to hit Osceola Dragway in Osceola, Indiana quite a bit too, it's a fun low pressure old school track.

Had high hopes for Onondaga Dragway reopening, but that pompous jackass who has been fighting them keeps screwing that up by dragging them into lawsuits.

I'm in Coldwater.

I've never been to Osceola, but I just looked at an aerial photo and it looks nice. About a half mile of shutdown?


Here's what's up with the rag joints. The old one has a lot of missing splines (red arc) and a flat spot (yellow line) where you can see the input shaft splines dug in.




The new rag joint is not missing splines, and it also has a flat spot.




The input shaft has no such flat spot.




Do I go ahead an try the new rag joint, or should I find a different solution?




Edit: Wow, sorry for the mega-huge pics!

The one you have is the correct one. The 'flat' is intentional.

Excellent! Is it designed so the input shaft splines will bite into the flat in the rag joint?

Yeah, that's not the right rag joint for the shaft in your picture and it won't work.

Looking at you shaft pic....are you sure that is a stock 1970 manual steering box?

Stock would be a Saginaw 525 box, 3/4"-30 spline with a flat that would match that coupler.
Reason I ask is the stock 1970 manual box, the 525, has about a 5" long input shaft....in your shaft pic it doesn't look like you box has a shaft more than about 1-1/2" long??

Here's what a manual steering box for a '70 Nova looks like:



The O.E.R. rag joint does work on this style box.
