hello Jim
36mm, thats the size of the biggest socket in my tool box. (It also helps for the weight).
there are hollow shafts on the GpA car here, the shafts are light and yes, the wheel nuts are all the same size, makes sense doesn't it.
I've been looking at getting new hollow shafts made, looking at the most cost effective options. as long as the hollow shafts can take the torque from the new engine. Also lighter plunge joints are on the cards.
