Can't get a break

Might be a long shot, but dads was a 67 and we messed around with it so much we just decided to get his 150 speedo and our 2 tachs upgraded. When we took them in, the guy at the repair shop said..."yer missing the bushing from the back of the speedo"....Dad looked at me with that look that took me back 30 years( I just looked at the floor) LOL Dad had been saying all along about a little bushing....Dad was right I was wrong....We left the speedo there anyway as we had made the drive. Sorry for the long story, chk for the brass bushing...67 only.
