Here is the 26 spline LSD sitting on my bench ready to go into someone's diff.
Shiny thrust washer
I stripped it, cleaned it, measured everything and there was virtually no wear. I've installed an oversize thrust washer to tighten everything up inside and put it back together.
These are getting more expensive to source, so this is the last 26 spline unit at this price. If I decide to do them again, the price will have to go up.
£300 installed in your open diff casing or I can post as is.
Back in the UK for the summer, maybe longer......
