The 1992 GMC Suburban came from the factory with R12 not R134. Unless it is has been converted to use R134 you cannot simply add R134. If it has been converted you need to have the leak fixed before adding anything. It is illegal to add refrigerant to any system without first repairing the leak. How much it will hold depends on how much leaked out.
