I dont know where you getting your spares from but there not £7/8 for a wishbone .. more like £3.99 for one and if you think about it AE/schumacher/losi are 7.99ish for two ..
i know this as i sell the stuff ortho i will say the hudy drive shafts are alot at 22.50 for a pair
i would be checking the price you pay for stuff as you could be beeing ripped off
