The best way to fix a Prestolite distributor on a Jeep Dauntless is to replace with either a window-cap Delco or an Odd-fire HEI.
Have you been to the www.earlycj5.com forums?
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.
