NX2000 transmission issues? HELP!

[ZacJohnson]

Its been a while guys. Picked up a NX2000 which I love but i lost 5th gear.. what transmissions will fit this? If jason sees this.. do you have one at the shop? i saw the axles for it but i didn't know if a B14 LSD would fit it.. helP?

It's my understanding that they'll all fit.

B13 no LSD
B14 LSD
B15 LSD
G20 LSD

Not sure which is better but I know the G20 is harder to get.
