C6x Gear Set Part Number

Folks,

Wondering if anyone can help me identify the Toyota P/N for the 6th gear set (0.725 ratio) from a C60 gearbox?

Listed here for MWR:

Would like to find out how much Mr.T charge for it, as it might be an option for me to fit to my recent daily driver Celica T-sport (would drop my 6th gear cruise RPM by about 400rpm on my C64!)

Tried a Toyota parts site, but doesn't show 6th gear set for some reason..

Cheers,
Ross

Found it anyhoo.

C60 6th gear (0.725 ratio) - 33037-20010.

Not cheap from Mr.T, but can be sourced else where much cheaper.
