setting up a slash with 3s and 9l

would a 54 tooth jato spur and 15t pinion fit under the gear cover? better question is there enough adjustment to make these mesh correctly?

I don't know what the difference is either, it can't be much. I thought they were the same as well, but 2 different part numbers. Somone on the traxxas board put some different wheels on it, and they commented on the difference.
