anyone know any companies the make new motor mounts or inserts for the automatic platforms? I found out the Prothane does not after i went out and bought a set.
 
the driver side motor mount works fine. looks as thought the trans mount will work as well surprisingly but the front and back seem to be way to small.
 
Front, rear and cam gear side should fit fine, trans shouldnt because the hole is offset with the auto trans unlike the manual that is centered.
 
Your best bet would be to get a newer condition OEM mount for the trans and fill it and replace all the other ones with new poly mounts. Or you could use full solid mounts all the way around.
 
Agreed... Your best bet it to go with a new(er) OEM mount and fill it with DIY polyurethane.
As for the AT mounts, the only aftermarket (ES or Prothane) mounts that ARE NOT interchangeable with the MT mounts are the forward & rear mounts. With some coercion, the Prothane insert for the front mount will work. The rear 1G AT mount will not as it has a much larger diameter then the MT mount.
I was able to get some pretty good used mounts from the bone yards. Once I cleaned them up and removed all of the flashing that it on the inside of the rubber inserts, I fille dthem with a 2-part polyurethane found here:

Here's a pic of my rear 1G AT mount... I ended up going with the custom filled front & rear AT mounts and just used the 2 existing passenger & driver's side mounts from the Prothane kit that I got a while back.

I bought a manual kit for mine and the trans mount and belt side mount were correct, the front was just a stiffener (if that's what you wanna call it) that worked with the existing rubber but the back prothane insert was much smaller, like 3/16". I just made the rear one work. And WOW i never new how stiff they really are until i ran it for the first time. It really shakes when your sitting at a red light.
 
The issue for me with my auto 1g is the the rear of the motor is sitting on the frame so i need to lift it up how should i go about this cause i need a new rear mount in order to lift the motor from the frame?
