T1 diff query

[Chris56]

I have recently purchased a T1 touring car chassis which is in very good condition except the rear diff crown gear is becoming worn and is slipping. I have swapped the front and rear diffs, shimmed them, and this has made a difference however it is inevitable that these gears will have to be changed after a few race meetings. Will the X10 gear fit on the T1 diff? (the one that is available on the Teamxtreme website)
I am aware that I can do a Tamiya gear conversion, but would like to avoid this if possible.
help please???!!!!
