Yes, I have posted the specs of the Pantera driveshaft on the picture above^ the outer end is 8mm and the inner end is 7mm, as long as the Serpent (I think I will go with the 950R setup) has the same size driveshaft, the only other thing would be the size of the bolt coming out of the pivot balls, the BMT is 5mm.
You are saying that all the modern 1/8 scale cars have the same size driveshaft ball? If so, that would be awesome!
