Stop in for a cup of coffee
I have never been able to find a good used one and that was in the 80's! My 74 was cracked also. Pulled a interesting distrib from the old box yesterday to start making a dent in them turned out to be a 57 Desoto 8. Came out nice but of course the vac advance took a crap after cleaning it! Actually was able to get one on flea bay.
