As you know, I changed to a 9" rear end. Also, I was having problems with the rear half of the exhaust pipes rattling against the new rear housing and leaf spring hangers so had that replaced.
I have driven the car but up until Tuesday had not gotten above 45mph. Well Tuesday I drove the car to the golf course and got up towards 60-70. When at those speeds, I have a noise I will call it. I can also feel it in a vibration. Worries me.
I have the car up on jack stands right now trying to see if something is amiss. Any input? Checking the driveshaft for issues. Not sure what it is, but if I can't locate the issue, Roger would you be willing to go for a little ride and see what you think. I will keep it under 100. Unless someone wants to race. Larry
