the drive axels on the lst are the same dia. as the center shafts on the lst2. The lst2 has thicker drive shafts, so does the muggy ( at least mine it was changed a bit as I bought it used so cant say for sure). The axels off the lst will work as a center shaft for the muggy/ lst2, its the same Dia. as stock, not skinnier, same as. just longer, obviously same length as stock axels ( not known offhand) So it should hold the brushless just aswell as stock, provided it doesnt hit some centrifugal weakening point Briang can calculate (dont hit me)
