GM HEI mopar dizzy hybrid

How about the nylon thrust collar with the washer and roll pin for the dist shaft. I went to my local dodge dealer and was told its serviced in the distributor assembly. I cant seem to find this aftermarket either. I used to be able to buy the slant 6 one and cut it down for V8 use. Anybody ever have to get one if these? Where did you get it from, mfg , part # . My other option is to bribe a machinest friend to make me one out of aluminum using the broken one i have that i super glued together so he has a template.

Anybody hazard a guess on the O ring too?

Thanks
Matt
