1/8th diffs with hybrid bulks

[tashpop]

i read somewhere in the forums that any 1/8th diff set will fit in the bulks for the maxx's, you just mostly shop for the right gear ratio's. i happen to have a gs storm buggy and storm sut rollers, both rtr modles, which to my knowlage have the same gears. i want to use the gears out of the sut if they will work for this upgrade to my emaxx. would this combo work or do i need to just buy some? if so, this upgrade will come later than sooner. thanks in advance.
