Default Replace dual AC Capacitor with 2 single cap's

Replace dual AC Capacitor with 2 single cap's
(apologies if you've seen this elsewhere)

Greetings,

I have a GE dual (fan and compressor)
capacitor # 97F5360 from a 2-ton Carrier 'round one'
circa 1984. It has evidently failed. The Condensing Unit is
getting lo-voltage current, but neither the fan nor the
compressor will even click.

The specs on the cap. are 25/5 mfd, 440v. Evidently
it is not practical to find a replacement part.

I'm told that it should be practical to wire 2 cap's
to replace the 'dual': a 25 mfd for the compressor,
and a 5 mfd for the fan.

The 3 terminals on the old 'dual' were wired as follows:

Terminal Post Color(size)
________ ____ ______________
Fan 1 brown(skinny)
Common 1 black(skinny)
Common 2 yellow(fat)
Common 3 yellow(skinny) and brown(skinny)
Common 4 yellow(fat)
Compressor(HERM) 1 blue(skinny)
Compressor(HERM) 2 blue(skinny)

A "Fine, Fine Feller" advised as follows:

"All you need to do is take the wire off F and put it on the
smaller cap then take the wire of H and put it on the larger
cap. Put the remaining wires from C on the open terminal on
either cap and run a jumper from that terminal to the other
empty terminal and its done."

There are 4 wires on the 4 posts of the old Common, and only
4 posts per terminal, so it's not practical to wires all 4 +
a jumper to the Common of either of the new cap's. So
perhaps I just wire, say, 2 to each new Common and add the
jumper. Could look like:

Cap. Terminal Post Color(size)
_____ ________ ____ ______________
5 mfd Fan 1 brown(skinny)
5 mfd Common 1 black(skinny)
5 mfd Common 2 yellow(fat)
5 mfd Common 3 JUMPER(fat)

25 mfd Common 1 yellow(skinny) and brown(skinny)
25 mfd Common 2 yellow(fat)
25 mfd Common 3 JUMPER(fat)
25 mfd Compressor(HERM) 1 blue(skinny)
25 mfd Compressor(HERM) 2 blue(skinny)

I have found a source for the new cap's. It looks like I
have room to mount them in the unit.

Does this look 100% practical? Any/all advise, etc much
appreciated.

Thanks,
Puddin'
