Stampede diff help

[Savage03]

Thanks guys! No I havent ran it yet, for one its been doing nothing but raining here, finally! im in california and we have needed it even tho it suks. Plus im kinda laid up right now, I just had surgery on my arm Thurs. so im quite a bit of pain. Just put this together last night cause its hard to look at new parts and not wanna put it together! hahaha.
I have the alum. idler as well, I also have the metal drive gear I gues its called, ones on the spur gear shaft. I may buy the ones from Mike as well then get the diff gear also if I continue to strip mine. Its been mentioned that maybe the reason im stripping them so much is cause I have atretched chassis and it puts more strain on the gears cause instead of wheelying and letting off the gas its able to stay planted, think thats true?

Since a couple of you have had all flm stuff can you answer this, can you use the stock plastic skids/braces on his chassis?
