Gearbox mount replacement
Discussion
As the whole rear suspension, Diff etc are off for overhauling I decided to replace the gearbox mount.....
I jacked the box up and the old mount came out with very little trouble. The new, though, won't go back in as the mount is taller by about 3/4".
I can't jack the box any higher as the rear of the gearstick linkage is touching the underside of the transmission tunnel.
I can't see any alternative to splitting the box and sliding it backwards to get the mount in.
Any tips would be greatly appreciated

. Sorry.The linkage is far stronger than the bit of fibreglass you're pushing it against
Another option............... uprated gearbox mount
New on left, old on right.
Bought from Burton Power as per the link on the uprated mount suggestion.
Slight difference in height caused by wear in to old mount. Socket used to prop it for comparison.
Top view. Slightly larger flange on the new one. Maybe cutting it down would allow a little more play to get it in.
View from under the rear of the gearbox. The brownish metal of the linkage fouls on the shiny aluminium plate. The black of the rubber gaiter is visible. I don't know if the aluminium is standard or has been fitted to strenghten or fill in a gap in the fibreglass.
The old one was levered out by prising it away with a screwdriver inserted in the central bolt hole.
There was similar arrangement to the uprated suggestion whereby a plate bolted to the chassis below the mount had to be removed before access to the central bolt could be achieved.

Take the lever assembly off the 'box! Three screws and it lifts out: goes straight back in again after the mounting is fitted. You may need to drill a hole in the fibreglass tunnel to access one of the screws - use a long Torx key (like an allen key). My set came from Lidl years ago!
Looks like a Type 9: current wisdom is that all 280/290S's have the Type 9 'box.
Here are the front 2 screws, viewed from above with the gearbox in place. It's the back one that I needed to drill the tunnel for.
You'll need to drop the 'box a couple of inches to lift the thing out. There's a plastic saddle at the bottom end of the lever: it should stay in place in the gearbox. But don't lose it (although it's available as a replacement).
Hope all goes well!

Console lifted to reveal two ally plates. The rearmost is on top of the transmission tunnel, the frontmost is fixed below and secured by the two screws shown attached to the rubber gaiter.
Rear plate removed:
Front plate slid back to show gearstick:
Enough clearance now to jack the box up and lever the new mount into place.
All fine and dandy, except that the top of the gearstick now fouls on the underside of the fibreglass strip that was above the frontmost plate. It only grazes it but that means it's sitting about 6-8 mm higher at least than before.
Here's the link to the new mount, as per previous posts about uprated mount:
