Mewgatech .154 pullstarts work if your lhs has them in
Spurs.. those are hard to come by. You can replace the entire clutch/flywheel with one from traxxas and use their stuff, but you have to have all the parts there to make sure you get the right ones. I switched to entirely traxxas t-maxx clutch and spur because XTM was out of stock (backordered) and I wanted mine to run rigt away.
