Whilst not quite that sophisticated I do have a pair of nice wooden trolleys I made earlier in the year, one supports a 4A-GE the other a C5x gearbox.

but they're matched up so that you can use them as a pair to wheel the whole assembly around.

Makes fitting or removing a gearbox from an engine

(out of the car) a bit easier too.

Will try and get some pics up to demonstrate if I can get enough space on the drive to get them out.
