For an under-chassis replacement I used a Cornell-Dubilier (CDE) DME series 
2.2 uF 400v metallized polyester film unit.  Mouser carries those.  They are 
about as physically small as you'll find.

Others have reported using run capaitors from small motors 
(non-electrolytic) and even AC line filtering capacitors scrounged from old 
computer monitors.  Mouser carries the line filtering caps as well-instead 
of a blob they look like a small block.

Maybe one of the above would fit in the old can.  Electrolytics are 
completely out of the question-too much leakage even when new.
