As above Sierra XR4 x 4

£150
+ postage

This is to finance new diff on TVR (partially)

In Devon although sometimes trvel as far North as Bristol !

Am I right in saying this is a 7.5 inch diff?
Do you know the ratio?

Thanks,
Craig.

I thought the XR4*4 diff was 7" with a 3.62 (LSD) or 3.64 (LSD) ratio?

But I could be wrong - it has been known.

I believe it is 7" and 3.62

If from an XR4x4 then it will be a 7" 3.62 LSD, (if it's the original diff). Cheers Ray

Unless its 4x4 DOHC 2.0L then its a 7" 3.9 LSD.
