Jeep prestolite distributor problems

A Delco is not much better. The 225's rattle the hell out of advance mechanisms, and the cap availability on the Delcos is not much better than Prestolite. I will say, it is likely parts are a bit more available.
The HEI choice, makes me wonder how tight it'll get up there. Looks like I may have to move a fuel line, not sure what else. I haven't even checked to see if the vacuum advance works on the prestolite.
