I've had a look for an 8 3/4" axle... they're like rocking horse poo over here

Besides, if they are the same backing plates I can still use the brakes if I upgrade the axle later

The guy I bought tha axle off said he had used his 8 1/4 brakes on an 8 3/4 so I'm fairly sure myself that they'll swap, just want to make sure..
