tranny vibration?

First, narrow down the location of the vibration.  Drive at a speed that causes the vibration.  Push in the clutch and let the engine drop to an idle.  Still vibrating?  Yes = something drive shaft related.  No = something engine/clutch related.

 

My guess is an out of balance pressure plate.  I replaced clutch/ rebuilt pressure plate and t/o bearing in a Ford truck and the thing would shake you off the seat at 2500 rpm's.  Replaced the rebuilt pressure plate with a new pressure plate and the vibration was gone.

Must have pulled the driveshaft out when replacing those parts. Possibly got the U joints out of phase?

That is impossible on most of these old mopars. Some do have a more conventional ujoint where it is possible though.

I would recommend that on top of rotating your driveshaft that you also go back and check that the tranny is flat and securely tightened to the bell and if you disturbed the bell on the block that it also is tight and flush fit..double check your work...also ensure that you got the rear mounts located properly and if they were soft and compressed that you did not inadvertently shift the tranny left or right knocking your driveline out of phase.

just use a modern car 12 volt battery to power your light separate from the car...all you need from your vehicle is trigger for the light...odds are that is induction unless you using a really old light and then it still does not matter..just T your induction per old style light...
