Transmission cradle

Someone asked about the placement of the spacer on the steering rack a 
while back. . .

Along the same lines.... A few days ago I took the rear transmission mount 
off of the transmission. When I dismantled the cradle from the rubber 
mounts, a shim plate dropped out on the ground. Both rubber mounts had 
already been removed so I guess that dirt and grease were holding it in 
place until it let go. Now I don't know which side it was on. Help!
