I was just shown this by a friend who recently bought a Toro-powered GMC motorhome. Golby Motor Corp sells parts for these motorhomes and has a new replacement front motor mount, which is the same as the unobtanium Toro mount. At nearly $100, it's not cheap, but that's probably less expensive than having Steele revulcanize an old one.

Hey Joe P.,
It IS cheaper.... Always talk to Lynne and Eddie from Steele -- they are in my aisle at Spring Carlisle -- and always stop by...
They call me frequently for N.O.S. motor mounts -- easier to sell mine, than to revulcanize!!

Their prices start at $100 & up -- and from the people who call me, there are more & ups, than the $100 !! And you still have to add shipping to them and shipping back, and waiting
4 to 6 weeks, usually...

So once again, you have found a way to help the Oldsmobile family.... That is one more reason that you are THE BEST.......
Yours, Craig...
