Thanks Dennis, I will add that to my list as something to look at.
I don't think its dragging. The car has a Flaming River gear box(bought it used last year from a guy on this forum).
I may switch it out w/the one in the Cuda. That box is a known entity and has been rebuilt by Steer & Gear.
Its an easy switch so I may just swap it out. The only items in the front end that aren't new are the upper and lower control arm bushing and strut rod bushings. Don at Hargroves said everything was nice and tight. I has already planned on replacing those this winter. With what I have in the car may as well do it all up right.
