The part number you need is TRA7079. When you get it, use the pinion and toss the ring gear in the trash. 90% of the axles I've done have required no extra shimming, but if you do need to add 1 or 2, Tamiya 53586 should work.

Best/easiest way is to open an account with Photobucket (what I use) or some other photo-sharing site. It's free and super easy to post pictures from them.

I see you now have a Photobucket account.
I know you started this thread for the overdrive mod, but getting those lead weights off of your servo mount will help waaaay more. I've seen a lot of people do that, and I don't know why; take the weights off and put them inside your front wheels. That will drastically lower your center of gravity and vastly improve stability. I even shorten the servo mounting posts on my rigs to lower the servo as low as I can for the same reason, it really helps with vertical climbing.

From what I have read, you need to either drill out your motor plate or order the Mini T "big block motor mount" from Full Force RC.
However, I actually have an Insane in front of me now, and it looks like it would bolt right up to the stock motor plate, but you may need to run a tooth or two bigger pinion if you don't want to drill the mount out a bit. I also see that it would need a spacer like this MRC Motor Spacer in order for the pinion to mesh properly with the spur.
Hope this helps.

I haven't run my Insane yet, but from what I've read, it has good wheel speed. Try playing with the gearing.

I think he meant what tooth pinion did you use on your Insane.
