Ok, don't label me a Moron, but... I am replacing the U-joints in my 70, and I forgot which way the driveline goes back in the car. Is it the solid end of the driveline to the front (transmission) or is it the side that has the smaller end that has a rubber seal between it and the driveline that goes forward? Basically my driveline is differant at both ends, one looks like it has a dampend end and the other is fixed and welded to the end of the line itself. This is my first Mustang, so be kind. My Camaro never had this dumb ass problem.
