hi guys, need your help. i run a stock rc12L3 with nothing changed except in-line axles up front. theres one other upgrade id like to have and thats a clamp style left rear hub. i know IRS has them but i just wanna be sure these are the right ones to get. saw some in stock at tower hobbies.

also, are there any other things i need to replace or have to make this thing work? i assume no and that i just have to replace the screw on hub that comes with the kit with the clamp and all else should remain as is ..... but just wanna be extra sure.

thanks!
