Capacitors -- replacements?

[Chuck Guzis]

List,

I've got a lovely old Lambda power supply here (linear +/-15, +/-5) 
that uses an old Sprague screw-mount (Computerlytic) capacitor.  It's 
rated at 34000uF, 15WVDC.    It's all dried out, so it needs 
replacement.

It looks as if it's going to be difficult to find a working exact 
replacement.

What in your experience works best in these applications?  Plain old 
"snap in" electrolytics?  Anyone have any hints on making the 
replacement fit the larger footprint?

Thanks,
Chuck
