Hi, I have an opportunity to buy a full complete SD1 rear axel for a good price, it's from a 2.6 Manual, is it likely to have the same diff ratio as the V8?
And would it matter so much in my MGB?

Wow thanks for that! Just read up on diff ratios, might be worth a punt to get the higher ratios and fit it into my shortened axel. £100 for a full SD1 axel seems pretty good to me!

There is also a 3.9:1 fitted to the 2000 manual. The auto has a 3.45:1.
The 2.85:1 EFI auto is comparatively rare and usually costs more.

Don`t forget that TR7 5speed axles have the same inner workings as the SD1.
