Thought I'd start preparing for swapping the gearbox, bought some Nolathane bushes to do the gearbox mount with but they aren't quite going to work without machining so I'll take them back and try some others.
I got out the LD28 C series box and what I was told is an RB20DET box and though I'd have a look at the difference, Mike (NZeder) said the LD box is just a B series gear set in a C series housing which it does infact look like.
I measured up the front gear including the thin secondary gear piece (whatever it is) and there's about 4mm difference in the thickness of the gear, all of the gears in the RB box are beefier than the LD one so I guess I'll fix the RB box and use that behind the FJ. LD box probably isn't much use for anything with any power.
This is what needs fixing, I'm almost certain this is what's wrong with the FJ box as well. When I bought the box the guy told me it just needed a new front countershaft bearing (and he'd even gone so far as to buy a new bearing for it) but when I got it home he'd obviously had it apart and saw that it wasn't the front bearing, it was the middle bearing and must have been too hard for him.
