Thanks for the reminder Jamee.....I got the Crown Vic aluminum driveshaft.It was about $140.00 total after shipping,and the work done (VERY well worth it.).They installed my yoke and flange with adapter u-joints.It weighs just a little more than nothing.LOL. It relieved 95% of the vibration.I think the tailshaft bushing needs to be replaced.I have a spare tailshaft that I can swap the bushing in then install later. As for now,the car is running very strong,and not enough vibration to cause me any grief or even hardly notice.With the T-5 there will be a little vibration in the handle unlike when I had the AOD. ....I had an AOD for so long the T-5 is still growing on me.As soon as I finally get used to something,I change something else and have to start all over. LOL.LOL.
