Rear diff? it's for a 1989 K5 full size blazer. I have looked myself here on CK5 and searched the net but can;t find anything /forums/images/graemlins/frown.gif I have just ordered my shop manual from a company here in the UK and I'm assured (or get my money back) it's the full GM manual, but I don;t have the time to wait for it to arive to sort this out and a diagram would help me out LOADS. So if anyone has got one or know of a place on the net I can get it for I would buy them a 'virtual pint' !!! /forums/images/graemlins/thumb.gif PS when I get my manual I'll be able to help out anyone needing it /forums/images/graemlins/thumb.gif regards, Kia.
