Unsual Rear diff Mount Question

Like just about all alltracs, my rear diff mount is shot. Anyway, awhile back I had purchased a rear diff to fully replace mine which was blown once, and I think is the cause of the really annoying whinning I get on the highway. Anyway, I assumed the rear diff mount on my replacement diff was going to also be junk so I bought the poly to fill it.

Well... ofcourse, the other rear diff mount that I bought is in perfect condition so now I'm torn on whether I want to fill it anyway or just put it in as is.

Looking for opinions. My first instinct is to put it in, and fill the other one so I have both available to me.

I'd go with the poly. The stock mount, even when brand new, is an amazing piece of crap.

Should I fill the stock one that I have that is good? (In other words is it okay to keep the stock rubber and everything as part of the mount and just fill with poly around it) Or just put that one in until I get the other one out, filled and cured?

I would put on the stocker. Heard of poly jobs lasting a couple of years then
crap out. The stocker probably lasted 10+ yrs and works just fine.
