RE: setup
I can't blow up the pics so it's really hard to see.
But if you can try to find a way to mount your servo like on a clod that will help.
As stated before move the shocks to the out side and if they perform well there keep it if you need alittle more articulation angle then back on the chassis a little. for an alternate shock use some maxx shocks or order some 90mm or 110mm from Run2jeepn.
It looks like the tranny is in a good spot and i'm not really familar with txt trannys so I can't help much there.
PM me if you need any more help. I'll try my best.
Posted on the RCC thread as well in hopes to get more people to look at it maybe.
