drive shafts :
I found this in my archives

"One of the guys at the track I race at also needed to replace his front drive axles and found that the offna 9.5 ones will work.I found that gs storm outdrive cups will interchange(for the center drive shafts) and also found that a kyosho outdrive will work in place of a stock one if necessary. The guy I was talking about used offna 9.5 front universals in place of the cvds because he was in the same situation as you.and it worked great for him."

and one guy said LST truck mid diff driveshafts are a fit at half the price ?
