1969 Dart Street/Strip (Re)Build
Over the weekend I got SOME things done. Was expecting to be driving it since I have all the parts I need but as usual, I keep running into hurdles. Denny and I are working through it though. I keep jumping from one end of the car to the other just trying to get done what I can. Feels like I have A.D.D. not concentrating on one thing at a time. The rear disk brakes are complete now with new lines. Once I got all the missing hardware, this was a total breeze. This is the Dr. Diff kit that uses mustang cobra rear disks and calipers. No more proportioning valve either.
Once I got the disks on and was spinning the driveline, I thought my eyes were playing tricks on me. I could see from 5 feet away what I thought was the driveshaft moving up and down. So I put a dial indicator on it and sure enough it was wobbling .038 out of round! It was completely visual to see too. You could actually see the driveshaft wobbling! This really wouldn't irritate me that much except for the fact that I've been fighting a driveline noise and shake for a year and a half. Last year I took the driveshaft in and had the u joints replaced and all balanced. It made no difference whatsoever after I reinstalled it. Pinion angle and everything else was checking out so I didn't know what else to check. Now it's looking like the shop who balanced it somehow didn't catch the bent driveshaft. How they could have missed this is beyond me. They turn driveshafts at 3500 rpm so it should have been easily caught. I'm going to take it back and give them a nice *** chewing and get them to fix it like they should have the first time.
