73 340 spool mount k-frame

k-frame is sold, sorry.

about your questions. there is no reason to have the washer. it does nothing. i have been told alot of stories for the reason of them putting it from the factory. the most prevailing was to know that it was set up for a 340 car.

now for the years. every single 70-71 duster/demon, and 70 dart 340's that i have had and seen had them on it. but from like 72 to 74 340 or 360 cars, some had it and some did not. this k-frame does not. i have seen other 73 340 cars not have it, and senn some with it. so i do not know. it has no funtional purpose
