I decided to go ahead and put the new capacitor in. When I Was testing the test button, I noticed that it took nearly half a second for the test button to fire again allowing for the capacitor to charge up. So while the old capacitor does work, it was in the stages of drying up.
I simply took the black cover, took the new capacitor, and coiled up the ends of the leads until they were at the edge of the black cover. Then I took two small plastic rods putting them thru the coil on both ends so that it holds the ends just above the lip of the black container, and taped that off (making sure the capacitor was matching the same polarity as marked on the black casing). Then I pushed in the new enclosure, poped a battery in and did the test button trick again, this time the test was firing instantaneously each time. The solderless method works for now and its in there pretty securely, the casing prevents for any accidental discharge. But even if it did dicharge in my hands, I likely would not feel 100uF/35V.
But least kudos to canon for having a removable capacitor as opposed to being soldered on a circuitboard like most the others. (They probably only wanted to deal with wires and connectors, no bread boards). But then again I don't know how feasible the technology was back in the 50s.
