Hi Jarvis, I was having a little look back at your build diary, wondered if you or anyone could Let me know the type and where you got your drive pulleys from. Iv searched a few sites so far but its like a mine field with how many different types there are. I currently have wheels mounted directly to the output shaft of the gearbox and after some vigorous testing this weekend I'm wanting to change to a dead shaft with pulley driven wheels like your rear wheels. After a big impact it seems it would be easier to replace a bent fixed shaft than it would a gearbox shaft. Lol
