Looking at some electrics on my 300F. The only numbers I could find on the starter relay were RAM-4001 and 12v. RAM-4001 it seems is an Autolite #, it cross references to 1842550. That, says my book is the correct relay for the PC1, ie the Windsor. RAM- 4002, Chrysler # 1842546 is the correct relay for PC2, PC3 and PY-1 . MY question is "What's different?". Looks as if RAM-4001 has been a long time on the car. Another wee query. The starter motor. I can't find the correct number 1889200 stamped on it anywhere. Maybe it's not the correct one. There are a few numbers randomly stamped, nothing I can make sense of. Anybody have some digital pics, or otherwise of 1889200 that they could send me to compare. Thanks, Dave [Non-text portions of this message have been removed]
