The voltages for that can are: 2mf-300v,  1-1mf 350v , 1mf-450v.
Would use the 630 volt caps for all and not worry about trying to match the voltages. If you use ecaps 450v should work.
Here is a picture of the one in mine It uses the standard can clamp.

Thanks - exactly what I needed! I even found a can clamp in my junk box that matches the mounting holes on the chassis!  Looks like in your photo that the original was an electrolytic, from the vent on the top. I was planning on using film capacitors, but ecaps would be cheaper and obviously must work in the application.  Thanks again.
