That's with the seal boot in the picture. Seems a bit overexposed to me.
I do have a bad vibration in the driveline I was told is a bad transmission mount, the more I look into how this suspension was all setup I’m going to have to check pinion angles and now you’ve even got me thinking a wobble could possibly come from the yoke being poorly engaged and possibly causing play in that ujoint as well
Can you show a picture of the tape measure measuring the yoke spacing?
2 more measurements, center of front uj to center of rear uj. and center of front Eye bolt of the leaf spring to the center of the locator pin in the differential leaf spring mounting pad.
Looks like the driveshaft is a inch too short1 3/4” exposed and almost 3” from the tail shaft. I looked through the documentation I got with the car and the driveshaft was shortened in 2016 to “measurements given by owner” the owner in question was the gentleman who I bought the car from who did the driveline conversion from /6 to 360/727 and 8 3/4 rear, hopefully someone can chime in and mention about how far it should be seated
Also in those documents I found an install instruction for the mopar spring relocation kit, and the instructions are foggy at best... I can see how someone going off their instructions could make the mistake of installing the shackle mount wrong, still not sure if this is the actual mopar kit, I’m still guessing home made

48” Center ujoint to ujoint on driveshaft

The front spring mounts and the springs control the rear end. If the rear end were a inch back, the wheels wouldn't center in the rear wheel openings. The driveshaft was modified and made too short it looks like.Definitly , rear end being back too far would do that >
That's a bit short. When I had my driveshaft cut and balanced it was 48 3/4 c to c on the u joints.
I didn`t go back and look but weren`t there 1/2" spacers welded in the front to move the rear back ? Some guys do that to help center the wheels in the wells.The front spring mounts and the springs control the rear end.

There's your "almost an inch" I saw on the tape measure.That's a bit short. When I had my driveshaft cut and balanced it was 48 3/4 c to c on the u joints.
No spacers, just a relocation kit. now if it was home made it could be the wrong dimensions.I didn`t go back and look but weren`t there 1/2" spacers welded in the front to move the rear back ? Some guys do that to help center the wheels in the wells.
Boy, it sounds like a comedy of errors. Lots of different things that need corrected. The rear hangers and driveshaft length for sure.In post #7, I'm led to believe that there's a 727 transmission in the car. Can you verify this is and isn't a shorter 904 trans?
Check with a supplier. Some recommend 3" minimum spline engagement. Others say 1" before bottoming on the output shaft (not seal) at ride height.I measured its showing 1 3/4” of yoke, not to familiar with these to know if that is adequate or not
Agreed. If the wheels are centered then the front hanger is in just about the right place. There could be a spring issue if they were changed. I remember seeing a chart with the measurements of the Mopar springs. I will see if I can find that. The springs could be an issue but not likely.Just for grins and giggles get the tire to fender spacing. Front and rear of tire.
