Wima capacitor ID

[Oldskoolfan]

Going through a fleece bay parts kit for a Pioneer RG-1 and I'm finding some questions.

Can anyone tell me if I can use this cap?
It appears to me to be a 1uf 63v film cap (not sure what M stands for). The parts list calls for an electrolytic.
What raises the question is that the schematic shows electrolytics both polarized and non-polarized in the signal path.
I believe I've identified C1 and C5 by process of elimination. They were supplied as Wima film caps.
C43 is electrolytic, has no indication of polarity...non-polarized?
Left channel illustrated, right channel similar. BTW, kit came with no parts list, no instructions. Joe spoiled me I think...

M is the tolerance grade, M=±20%. This is part of the datasheet for the cap easily found on Mouser or Digikey or from Wima.
You can replace polar caps with non-polar caps.
Yes C43 is a non-polar cap.

Buy your kits from peace.love.music / affinity for artifacts, a regular ak member that puts together quality kits and sells on the bay. Not someone that just stuffs bags with parts.

Got this kit early last year from Marblehead audio...lesson learned...

Yeah, that cap does not have a polarity indication, as the other two do.
