When I'm search for electrolytics. I go to Mouser's capacitor page and apply some filters.

For example, check stocked, select 82 uF, 450 Volts and Radial style.
You'll get this page of only four choices - all pretty good.

Here's what I ordered from Mouser for the similar 20X1 Admiral chassis. Note that I like to restuff the electrolytic cans so get long skinny radial caps (both leads coming out one end).
If you're going to install the new electrolytics under the chassis, you might find it easier to use axials (one lead out of each end).
I also round up the capacitance to the closest value and try to go a little higher in the voltage rating.

As for the paper caps, I live to use polyester film either Cornel Dubilier (axial) or Cornel Dubilier / Nichicon / Panasonic (radial and cheaper). I just go with 630 volts for all. Here are some examples.
0.047 @ 630v axial

0.047 @ 630v radial

Hope that helps.
