You can swap in a fuel tank from a 73 to 91 Suburban (Blazer). They have both a 30 gallon and 40 gallon option. Since you have a long bed you might want to try the larger tank to keep the big block happy... Do a seach and you will see the swap documented.

The rear is probably an Eaton HO52. Some guys like them, other dont. Brake parts might be a little harder to find. Depending on what your plans are, you could always swap it out...

Before swaping cabs, you better check into issues with the VIN. IF the blue/white cab has a title and the all white cab doesn't, how whill that be addressed when you complete the swap?
