    Have you tried doing an rpm run up in neutral to make sure the vibration isn't something else?

    That's the info I was looking for. Thank you. The one in the car measures 52" center to center of u joints, I'd say we got the right one.

    I installed the new poly tranny mount last night could not test drive yet because of rain. hoping to do that today, there was a big difference in height between the old and new mount, new one is 3/8 inch taller which then changes my angles and ended up removing axle shims I added last week. Now the angles are correct as they should be with no shims anywhere, kinda got me thinking this could be it. The old mount was old dried out shrunk'in thing. I will know for sure this afternoon....

      How much up/down side/side play does the yoke have inside the tail shaft?

      It had some movement, enough to see it , so I put new bushing in last year. The old one did'nt appear worn and the new one left me with about as much play as I had so then I bought new yoke and complete driveshaft balanced from Driveshaft Specialist out of Texas. Still about the same, I'm not sure what normal is but I can move it up down side to side enough to see and feel it moving.

      Look at driveshaft make all the clips are in place. If one is missing could cause a vibration. Long shot.

      Not sure what size (OD) of the yoke is supposed to be, but you could look that up and measure yours to see if there’s any difference.

      I've tried two different complete d. shafts one used and one new with new yoke and the vibration is exactly the same, no variation of any kind so how much play is "normal" in a front yoke? One other thing left.....can anything in the rear end cause alot of vibration without making any noise? This bad vibration started when I swapped gears, I swapped with a complete restored rear end... housing, brakes and all. the rear is quiet no rumble, or bearing noises or gear noises. there seems to be some play when I have rear tires in the air and turn them forward and backward it seems sloppy.

      At this point it seems pretty obvious the problem isn't in the driveshaft.. And since it started with the rear axle swap......

      Does the yoke on the rear end move up/down?

      No, yoke and u joint feel tight. I can only think bent axle maybe?? I'm thinking I'm going to pull the pumpkin out and go back to 3.23 gears and while I got it apart look for anything wrong. I'm out of idea's and running low on hope. How can a vibration so bad be so hard to find?

      Check all the bolts and front/rear spring hangers.

      They are good. I got it on hoist and going to start taking rear end apart, check out ring and pinion preload, check for bent axle or bad bearings in carrier and axles.
