Where can I purchase a LSD centre?

[RXed Midget]

Hi Guys,
I need help...
I have a MG Midget with a Ported 13B Rotary engine, RX7 5 speed and the diff centre housing is from a MK2 escort (3.5 gears), however the front flange is Mk1 Cortina.
The axle housing looks like Mk1 Cortina or Anglia with the Sprite handbrake linkages attached.

My problem - I need to obtain a LSD centre (hopefully around 4:1) - ideally keeping my housing. The centre will need to be able to handle 200RWHP.

Any suggestions?
Is there such a thing as a MK2 Escort LSD?

Attached are old pics of my diff. If someone believes I am wrong with the model it originaled from, please let me know as I am from a Rotary background, not Ford.

Thanks
Malcolm

You can get an LSD unit easy enough from the UK or local suppliers also stock them such as SMCKA Performance in Sydney. I recently bought some new 4.4 gears from Burton in the UK. They pretty much have any ratio you want for these diffs. Just make sure you look at "English axle" and not "Atlas" or it wont fit your diff
