I've put up a couple of photos of the two spare gearbox mounts on a web site :
www.rathluba.com/ute
There are substantial differences between the mounts, the oily one ( which was on the ute prior to the respray) appears to be bonded at the bottom as well as the sides, the one with the holes on the plates is a genuine Toyota part but does not have the bonding on the bottom which would explain the "bounce " I'm getting as the one on the ute at the moment is similar except it has'nt got the holes drilled and tapped in the mount.
Looks like I'm off to the nearest Toyota wrecker to see what I can find.
