The plot thickens

I was going to post a new thread about a new problem but I guess I can still relate it to an original post since it is about the same 340. After installing the new factory Mopar distributor and orange box the 340 still fires but doesn't run. That's the same old problem. However, the new problem I am speaking of is I noticed my new Mopar distributor wiggling like a dashboard Hula dancer. Unfortunately that is not much of an exaggeration. I went ahead and pulled the oil pump driveshaft. It is galled just below the gear where it rides inside the bronze bushing. So, would this "wiggling" of the distributor cause my motor not to run? What would cause the shaft to gaul in the bushing. Is it possible my cam is moving causing pressure on the shaft? I ask this because the motor was previously in a bad accident while the car was parked. The motor seemed to run fine after the collision. I even drove it out of my neighbor's yard. However I soon pulled it from the old Barracuda and ditched the old electronic distributor in favor of the cleaner Mallory Unilite. That one lasted for about two days after dropping the motor into the 69 'Cuda. Yes 'Cuda, not Barracuda. On a side note I recall seeing this distributor wiggle around as well. I just assumed it was a bent distributor shaft. Four distributors later I am at a dead end. Any ideas are greatly appreciated!
