I'm in the UK and wondered if anyone over in San Francisco could score me some....................

Actually, I would like some advice about fitting a differential (either Limited slip or torque biasing). I've heard that the originals are hard to source. I have also heard some negative feedback about Quaife who are the default diff over here.

There are a few ads in Excellence. Any opinions ?

Any help would be gratefully received

Cheers

Mike
