Hey guys, my fasty may need a new gearbox.

What is a reasonable price for a swing axle gb (decent secondha) and installation???

Just don't wanna get scammed, and money is tight.

If you're worried about cash and are at least a little handy with a spanner you could do the swap yourself, Just invest in a good manual and she should be apples.
cheers

I'm a bit of a novice, wouyld look to do stuff myself down the track, but not just yet.
