drive shaft question

A rather belated update. I installed the driveshaft and got the 360 fired, got about 200 miles on the Barracuda. No strange vibrations, it's a joy to drive! I'm guessing the driveshaft to be where most of the vibrations were coming from, but I can't rule out the missing bushing on the tq snout, or the weights on the right front brake drum that were keeping the wheel from seating properly. Whatever it was. it is fixed!
