With the current exchange rate, only

do you know if it will fit an O2T gearbox too??

I can ask when I get back home on Friday night. There's no mention of it on his website though.

yeah, sometimes they dont mention that it will also fit other gearboxes, but quite often you find that there are a lot of shared parts which can interchange...

The diff should be different (lol) on the O2M, he multishaft gearbox has a different internal arangement than the smaller five speed gearboxes, certianly different bearings and casings.

Now on the lookout for a DRW (long ratio) 6 speed box to put it in. Anyone know of an 03 or 53 vRS in a scrapper?

How about making the final drive taller so all gears get a bigger range? No clue if this is a reasonable alternative but if it is, I'd do that instead as the more recent box keeps 6th closer ratio to 5th and let's face it, 1st and 2nd are pretty much useless at the moment, slightly taller gearing might get 2nd somewhere near useable again?

as it so happens, these people had one last time i was there!!

clicky clicky

a bit of a long journey for you tho mate

What does a diff do?

This link pretty much explains it: Howstuffworks "How Differentials Work"
