1.5 lbs heavier, most definitely stronger, disappointingly less effective looking cooling fins.

Thanks for posting the side by side. I guess I'll be getting 3 of these soon. One for each gear ratio. Due to the location of the weight, I'm not worried about the extra 1.5 lbs.

Bummer, now the diff will run 350*F instead of 340*F.

Looks like there are at least two different designs... the one that Bob posted with the cast in triangulation and then this one. The top side looks pretty much the same as Bob's. Either one should work fine, yes?

Yea the salvage yard had two different looking ones I think the one I got was a later year range FC. The big pad on the bottom is different as well. The ring and pinion on the diff from the one I got was blown up so I got a good deal on just the aluminum part.

I can guarantee the CVs used on the MSM axles won't do that, if only because they don't have any ***** in their CVs. The MSM uses tripods.

I have no idea if the tripod joint has a higher torque capacity, but the guys at Taylor probably do.

Problem is the Mazdaspeed Axles won’t fit the OS-Giken or my spare Torsen that I currently have. so besides the cost of the axles it’s an expensive swap. I'm pretty sure the tripoids will handle torque better. I haven't blown any axles up yet but the noticeable wear and sloppiness they develop has me replacing them every season.

I bet the splined pieces insides the giken can be had for reasonable money and will drop right in the one you have now.
