Solid roller questions....

So far, by using only the Mopar Performance intermediate shafts, I have found that by installing the bushing the proper way, I have experienced good wear. If I ever find that I start getting cutting lines on the brass I'm going to have to develope a tool to drop down the distributor hole to check the actual depths that are destructive. I learned about the gear depths while working on big block 460 Ford that was destroying brass gears left and right until we reset the gear depth to the factory specified depth. We had a stock distributor that had been modified to fit under a sheet metal tunnel ram and they set the gear on incorrectly and the brand new MSD distributor was wrong and chewing up the brass gear.
