ok dont laugh but is there something written on the sierra diff telling what ratio it is or am I going to have to do it the hard way and attempt to do it visually???

its limited slip and thats all i know

look in this thread,

http://www.locostbuilders.co.uk/viewthread.php?tid=17403

should be on the tag if its lsd then its either a 3.62 or a 3.92

there we go, a table off codes.

knew there'd be any easy way...

thanks.

oh dear looks like the tabs been snapped off...all that remains is the end.

yip got to do it the hard way now.

cheers anyway

It may be marked on the crownwheel if you remove the backplate and spin it over.

Is the donor car still around, check the chassis plate?

Thought I'd bump this thread instead of making a new one. In the link in this thread I found:

85GG 4006 DC --- 3.97
85GG 4006 BC --- 3.62
85GG 4006 AC --- 3.38
85GG 4006 FB --- 3.36
87BG 4006 GB --- 3.14

86GG 4006 AAA --- 3.92 LSD
V87BB 4006 BAA --- 3.62 LSD
V87BG 4006 CAA --- 3.38 LSD
85GG 4006 AAA --- 3.36 LSD

The code on my diff tag is:

V8*5EB4006AA
4A3625B14

So is it LSD or not?

Thanks for any help ^__^

* Hard to read this 8, could be a 6 or a 5.
