Ok folks, ran into a fair deal and had to make a parts run to Detroit. (Sorry for invading your back yard Marty) First off are these items. Distributors: (Hint for those thinking about the Pertronix conversion) The following are Chrysler Distributors WITH, I repete WITH, the stamped, marked tags present. model # Part # application 1AZ4001G 1658989 1955 and early 56 300 ( 331 ) ( could I make a killing with this one??? ) 1AZ4001D 1626660 55 Windsor?? Very possibly also early 55 NewYorker & Imperial (according to one source) 1AZ4001F 1641707 late 55 NewYorker & Imperial ( 331 ) (have 2 of these) 1BS4007A 1841515 58 New Yorker & Imperial ( 392 ) 1BP4006-C 1889564 60 Chrysler, Imperial, Dodge Matador (clean, looks like only lite usage, paint daubs still there, appears to be great for a total resto project) (MAY have original points still in it, the points have an oil wiper for the eight sided thingy) Dodge/Plymouth This one appears NOS (dual points) 1AZ4003-L 1626656 Early 55 Dodge Coronet & Royal late 554 - 56 truck V8 Early 55 Plymouth V8 (clean, paint daubs still there, appears to be great for a total resto project) (I did get a 57 300-C distributor, but so far I am hanging onto it, it had the red boot plug wire with it, should that be a Wahoo!! =;-> ) The above information is based on the references I have available to check out.
