Zf Diff Part Numbers

[ChevetteGP4Tez]

Hi, I have been offered an lsd for an Opel. The numbers on the main case are:-

4061006421

2251271

S45

and the numbers on the end plate are:-

307037.

I think there is a very small ZF logo after 307037 but its too small to see clearly.

Does anyone recognise the numbers on this diff and if it is for an Opel Manta axle?

Regards

Tez

Haven't a clue, maybe contact ZF direct????

The no. that matters is 4061006421. Ask this bloke what it fits.
