Hi guys. In need of some expertise, im looking to put a lsd in my scorpio car. What 7.5 inch lsd can i use to make this possible?

Which Scorpio do you have?
Early ones have an lsd I believe!

It's the frog eye shape and no they only came with traction control just not my model

Any 7 ½ from Sierra cossy will do
Most were 3.64

Will the drive shafts from my scorpio be the same or do I need shafts aswell

the sierra cossie 2wd has a 7.5" LSD with 108mm CV joints

your one has 100mm CV joints


ford LSD's use different flanges/stub axles in the diff - they are unequal lengths (your current ones are equal length in the open diff)

the only strait swap is for the earlier granada cossie one - otherwise you'll need to make a 7" LSD fit or change to the sierra cossie 108mm shafts and hubs

Would the internals from the sierra cossie diff fit inside the Scorpio casing?

^^^ that doesn't save you anything - as I fairly sure the casings are basically the same - its the stub axles/ flanges on the diff that are the issue

...well your one might have the other type of rear mount, but you only need to swap over the rear covers to sort that

The early Ford Scopio's ran a 7.5" 3.36 ratio LSD, the same as what is fitted to my Westfield Seight
