FLM rustler tranny case

[Sammus]

Howdy, I noticed on the FLM website they actually make two different versions - one with 1 deg toe, and the other with 4deg toe. Which one does RCM carry?

Also, I noticed that the pic in the RCM store the arm mounts have two holes in them, any reason for that?

Thirdly, if eg I did by the 4 deg toe version, and decided it was too much, can I buy the 1 deg arm mounts somewhere seperately? they dont seem to be listed in the RCM store or on the FLM page...

And lastly, is the FLM tranny and arm mounts compatible with the stock rustler arms and driveshafts etc? I think I remember reading somewhere that u need to use nitro arms, though I could be imagining it because I can't seem to find that reference anymore lol..

Cheers
