Vibration at 60 and up

[hemifiedbird]

I've run into this before where who ever had the car before had a mishap with the driveshaft. Instead of repairing it they went to the wreckers and got one there. Put it in the car and it vibrated. Went through the driveline and balanced the shaft and new joints. Found the problem was the shaft was 1" to short and was to far out of the trans causing it to vibrate above 60. Built the shaft to correct length from Service manual, Vibration gone.

well I got my new trans mount installed and against a lot of opinions from some of my mechanical friends the replacement has cured all my issues.Feels like a new 58 year old car!
The vibration was even noticeable at a certain RPM in neutral which means it was resonating thought the crossmember and under the drivers floor pan I think.
Glad its fixed
now my 58 year old body just has to beat this ******* blood cancer that has attacked me and my spine ! I go for a human type transmission fluid and filter change next week in hopes to make me feel well again !
cheers to all

Glad the car got done.

Now kick that cancer's a$$!!
