it looks like a bad copy of a phantom grip...

not an LSD as such, but just a block which is wider than the normal which uses the clamping pressure which is introduced by crownwheel being bolted onto the diff cage to lock the diff.. more like welding the diff up..

The phantom grip uses two spring plates which attach round the diff pin in normal situations provides a free diff but when one output shaft starts to spin causes a friction/turning action on the grip which tightens up the pinions and outputshafts..

Personally, I wouldn't use it as it'll put a lot of stress on the already weak diff pin.

cheers mate for that

bugger I was hopping that it would be worth havin I thought it may of been an old sailsbury type I knew it wasnt a quaif or more modern one.

you cant spin either shaft freely so i thought it must of been a plate one.

I'm fine with motors but dont do boxes
