Hello to all, I wanted my first post to be something usefull to someone, so here goes. I am in the process of doing the HEI distrubutor swap. Part of the modification involves filing off the hold down collar from the HEI dist. You can modify the original 235 hold down or come up with collar. A good source for the collar is McMaster-Carr. I found a two piece collar 1" diam. that fit the 250 dist perfectly.
