Will these diffs work in these bulkheads?

[Krawlin]

I am looking into getting some FLM hybrid bulkheads for my E-Maxx. I currently have a pair of Mugen MBX5-T diff's that I want to put in them. So my question is this, has anyone used Mugen MBX5-T diff's in FLM hybrid bulkheads? If so, how are they holding up? Do all 1/8 diffs use the same bearing sizes, like is it all basically standardized? Also, the MBX5-T ring/pinion gears are helical cut, and I have read that helical cut gears put alot of stress on the pinion bearings. Would I be better off going with 1/8 diffs with straight cut ring/pinion gears or should the Mugen diff's be fine as long as I have some good bearings?

Thanks for any help!
