how can i get round the problem then as the pic of the sieera diff is the same as mine

What problem?

The shafts are different lengths so that the diff is in the middle.

Or are you saying your diff is like the sierra's but your shafts are equal length?

Not sure I understood that?

You need to align the diff so the prop flange is (more or less) in the middle of the transmission tunnel. Because of the way a diff is constructed, this will mean the diff housing is offset to one side, which is why one driveshaft needs to be longer than the other.

I would look at the nissan where the diff came from and then set it up that way. i.e. - does the Nissan have the prop flange in the centre of the car or off to one side.

It's fairly normal to have your prop flange an inch or two to one side as universal joints work best if not in a straight line - nearly all solid axles are that way.

i solved the problem now it does fit it fitted from the begining the problem was that i took the drive shafts off and then but them on the wrong side so it would nether of lined up so thanks for all your help from the begin it was me being stupied
