I have two somewhere in my garage but I will probably never find them. They are black with a blue gear if that helps.

 

I've found white gear and yellow gear, does it have to be blue to be the correct one?

 

Just make sure you get the gear for a 6 speed that isn't for the MSM and it should be a 3.9...

 

I'm trying to get the same guy who's got 3.9 gears to source me the electronics gear, he needs a part number, and I've got more than one part number. Hoping they're all the same...

 

I've got 410s in the diff that's going in my build right now with a 6 speed. I'm going to run out of gear badly at Pacific where the MSM was hitting an indicated 140 in T1 with the 3.63s. I like those gears so much that I'm not willing to take them out of the MSM to put them in the track build so I'm either going to bounce off the rev limited for the last 1,000 yards of the strait or going to need to follow the advice in this thread and get some new gears...
