You need to buy a 32 spline input gear for your transfer case, and modify your crossmember. The adapter you have will work, same bolt pattern, just need a new gasket.

Which transfer case do you have?

Where do I find one of those gears for the transfer case? And I'm not sure exactly, whatever came in a stock 2004 SS Silverado AWD
