Part Numbers?
Hello,
Seems the original parts manual (1981) has the standard 5 digit part number with two aditional numbers after a -.
xxxxx-xx
It seems if new parts are approved or perhaps re-designed certified replacement parts are made, they get a 6 digit number xxx-xxx.
Is there some sort of cross refrence or guidance on this?
Just curious.
Recently I needed replacement fuel cap for 1981 PA32R, there is a newer design approved part but part number is xxx-xxx, just wonder how to search or look for other such parts.
Thanks
