Is a Quaife LSD simply an add on to the existing bevel gear and ring gear or do these parts also come new?
It's just the diff, it doesn't include the bevel and ring gear. I can't answer any of the BTR questions as mine is a Salisbury axle, but I'm sure Billy Bellinger would know. My axle was rebuilt 10 years ago and at that time it was no problem to get a Morgan ATB from Quaife, but I have no idea what availability is like these days. I'm sure they could make you one though.
