I really need to get a rear driveline built up so I can complete the design work on the rear end of my car.

Currently I have a 26 Spline 3.92 Push Fit Sierra Diff and a set of 23 Spline Push Fit Sierra drum brake driveshafts which obviously dont fit together

What I need desperately is to build it up properly so I need either:

A 23 Spline 7" Push fit Sierra diff (preferably 3.92 Ratio but any will do as I'm desperate) to fit the driveshafts I have.

or

A pair of 26 Spline Push fit drum brake type Sierra Driveshafts to fit the diff I have.

I would prefer something useable in decent condition but at this point I just need something so that I can take the measurements.

Can paypal the money over and will pay for postage.
