Thank you everybody. I appreciate the replies. I started digging through the cache of parts I have and I found a distributor with no noticeable play like the other two that I have. For the time being, I am going to use that one and see how it goes. This is going on a donor engine that was, I am told, a runner until the day it was pulled. It is a 1947 228. I never heard it run. I want to run it and see what it is about. I have a 52 or 53 248 that had been rebuilt a short time before the truck was ruined. Maybe 10,000 miles. That may be what ultimately goes into the truck later this summer. In which case, I will use the distributor that came with that motor. I would just rather keep this original truck as original as possible.
