A salvage yard an hour south of me reopened sometime last summer after being closed for many years. I went down last weekend to look, and maybe pick up a few things for my 49 Plymouth. I found a 55 Savoy with a L6, I got the generator w/bracket, voltage regulator, six blade fan and shroud, AC glass bowl fuel filter, really nice battery tray, an IAT 4101B distributor, and a few small odds and ends.
I think the distributor IAT 4101B may be from a 54 reading some old posts here. desoto1939 had a post from 2012 with a lot of information on this distributor number. Tomorrow, I plan to pull the distributor out of my 49 and see what number it is. The IAT4101B I pulled from the 55 may have been rebuilt before ending up in the junk yard, it was really clean and shiny under the cap.
I think I can go back and forth, if needed, with either of these distributors in my 49?
Someone bought a really nice DeSoto the day I was at the yard, I think it was a 50.
Thanks
Mike
