advance springs

what advance springs work on a /6? I have a distributor that I want to go thru for my fresh engine. I forget the tag number. It's the common one they used on the Super 6 engines, late 70s. not sure what the advance curve, etc is now but Im sure it's as made by the Mopar factory back in the day.

UPDATE; PN is 3874876

Plans are to dismantle, put any metal parts in the ultrasonic and make sure they are clean as can be, lube up the advance weights, and reassemble with new parts listed below, that I already have on hand.
I'm looking for some of the "lightweight" springs that were being sold a while back by a guy on the forums.
will the Moroso or Mr Gasket ones work on our engines? hopefully I don't have to have a pile of /6 core distributors to rob them from.
I have an iron gear, new NOS electronic pickup, and new advance can already, for this dist core that I have.
