Injectors on a 2004 5.3 help.....

I used washers and a longer bolt for my 60#ers. Either stack the washers in your hand and make sure its the right height, and tape them with a piece of tape, or use a little glue. They make machined spacers. But they are pricey. Washers look fine on mine. But dont run them without some form of spacer. The injectors can pop out and catch the truck on fire.
