Hello Tom, If this was my radio I would be using 500 volt electrolytic caps. I would not be under sizing voltage ratings. I buy my capacitors and resistors from https://www.justradios.com/ Yes the dual cap would be wired as you say. The red and green wires are the positive side and the black wire is the negative side. I noticed the dual 8 does not indicate the positive or negative side but the 10 does. Based on what Ron said the 10 should be a 12, check your schematic. I think both of your caps are previous replacements.
