As far as I know

85GG BC relates to a 3.62:1 dif ratio , Commonly fitted accross the Sierra range. :)

3.62 diff. Which is a mid range ratio and most sierras used. Should be good to use

Why the double posting
 

This was answered yesterday when you posted it :confused: :confused:

Here

I don't think you will get a different answer by asking the same question elsewhere on the forum.

If you have major concerns about your diff a little more background info would be helpfull :)

As it stands You appear to have a 7" sierra diff that has a ratio of 3.62-1 & is fine for the Roadster

I have merged all three threads into one as this topic is starting to get messy.

Hope this link works. ;-)

That explains the Differential Drive which is one component of the final drive unit. the other is the Crown and Pinion gears that Provide the Drive ratio.

Sierra Diff
 

Hi,
A friendly man at the local ford dealer let me use his microfiche machine and I've managed to get all the part numbers, FINIS numbers, exploded diagrams etc for Sierra, Granada and Scorpios. I'm putting together everything I've found at www.super7thheaven.co.uk
Hope that helps - It's a work in progress
