All parts are new, including the drive shaft. The front and rear are Disc brakes. Fronts off of a 71 lemans, and rears out of an 81 TA. I'm looking for a set of wheels to try and swap, inorder to rule out the wheels and tires, but haven't found any yet. I'll have to check the front rotors, maybe I need to have them turned, eventhough they are new. Could it be a motor mount, or something like that also?
