Yep thats what ive got on mine. That price is just daft. Look at the solution by gbs.
Do a search on the robin hood forum it could be done with just a big nut and bolt.
Drift the old pivot out, tap it to somthing like m12. Grind the head of an m12 bolt to a mushroom, wind it into the gearbox and lock it of on the out side with a nyloc.
One adjustable pivot point, cost a few pence.
