Thanks for the reply guys....

Size: 3100 short bed
Transmission: SM420 Muncie
Transmission change: I have been told there is an adaptor for the back of the trans to convert it for open drive line use?

twotone - did you change the motor in your truck?

If the rear end does not aid in the sound I may try and go to an open drive line. That would solve some of my oil leakage....


Take care,
Steven
