It is finished

Kim, I did. I replaced the tailshaft bushing. It was a little chewed. I cut the spring perches off and put a new set of them on and set the pinion angle at 5 degrees and drove it and it was still there. I moved it more until it was gone. I rewelded the perches and the angle came out to 8 degrees I believe. I went back to the 3:23 gears instead of the 4:10 and I put the new exhaust out the back. I think it may have been a combo of a lot of things. All I know is that I was very relieved when I got in it and drove it and it didn't vibrate anymore. Thanks for all the input. I checked all the things everyone suggested except I didn't find anyone who could balance the brake drums but since they were new I didn't think that was it.I have a wild notion to take it down to the "cruising the coast" in October.
