assuming you mean the front shaft for the rear of a YJ and the 2 u-joints on either side of the double cardan joint..... 2 3/4"

Yes, exactly!

2 3/4 center to center of the u-joints?

Thanks bud!

I was hoping you were a 1/2 inch off I'm thinking of running a hybrid slip yoke with a double cardan. I don't think I'll lose a d/s if I keep it as a slip yoke. I've had this thing flex pretty good, that d/s isn't going anywhere. I have very slight vibes now that I can't get rid of. 1" MML and 8 degree shims on the rear axle I almost got away with it

i assume you're running a different slip yoke to mate to the XJ shaft? the stock yoke won't work. you need something to bolt the XJ's shaft to.

I was thinking using the YJ slip yoke > double cardan > YJ D/S. I would have to cut the d/s down 3/4 of an inch or so.

I would remove the flange on the XJ and swap it with the YJ slip. I don't have a XJ shaft yet to see if it would work, I would think if the u-joint are the same size I should be able to do it.

Does the XJ shaft look like this?

Then again, why not just spend 160 shipped for a SYE and get the xj shaft cut down, needs to be cut anyways

I thought of doing that way back when....

It really is a crappy way of going about it.

Heck. Spend a buck fifty and get an sye.....

if you do go this route..... yes you will possibly eliminate vibes, but you still retain the "weak" slip yoke style output shaft of the t-case..... i snapped mine once..... not fun. better off to pony up and get a real SYE...

no, that's a flange mount style. the XJ shaft bolts up to an open end yoke like the YJ's front DS except the fixed yoke that bolts to the t-case is drilled through to pass the mounting bolts. the threaded part is part of the CV. you can see mine below.
