What are my options for a rebuild?

I know that Readman Racing are most often recomended, but they are up north, and I'm London based hoping for a quick turnaround

Are there any other options?

Might be worth seeing who TVR folk recommend as IIRC BTR diffs were used in Chimaeras. Also in some Morgans (not sure which ones).

What car is it for?

Some background on BTR: https://www.gomog.com/allmorgan/btr.html

Qualife do some replacement for BTR diffs e.g. https://shop.quaife.co.uk/shop/differentials/quaife-atb-differentials/qdh3m/

Cheers

It is for a TVR

I know the BTR is sometimes used on own builds, hence posting here

Looks like I'm taking the diff to Readman, as there are no used units around, and they may be able to turn it around in a week

Could be worth a call to road and race transmissions?

In Kent. They worked on my English axle and put right the bits that another well recommend firm put wrong. To be fair they do specialise in the titan diff I have.

But they seem to know their onions.
