Fried Q3 Cap Replacement

[msobeldc]

I'm a relative novice at this but am going to try and replace the binding posts on my Fried Q3 speakers. While I've got it opened up, I thought I'd replace the caps in the crossovers as well. I found a schematic on the web and purchased new caps from Parts Express. The 8uF seem to be polarized while the 12uF and 4uF are foil and seem not to be. Is there a trick to which direction the polarized 8uF has to be installed per the attached schematic? I don't want to screw this up since the speakers are for my daughter. This is my first project of this type, so I apologize if the question is stupid or I'm framing it incorrectly. Thank you for your wisdom and help.

The caps should all be non-polarized.

Thank you. Would these work? Dayton Audio:
DMPC-8.2 8.2uF 250V Polypropylene Capacitor

Does it look like this? If so it's non polarized and xsn go in either way
