This morning I wanted to change the throttle position sensor on the throttle body of my 90 K-5 w/5.7L eng. As I was removing the two screws they both snapped off inside of the throttle body. One snapped off right at the opening while the other snapped off well inside of the TBI. The TPS is being held on by just one of the screws and the truck seems to run ok for now. What I need to know is who sells the TBI aluminum body so I can replace it? This really sucks, something that should have been a 10 minute job has turned into a nightmare. This is my daily driver and I need to get the TBI replaces ASAP. HELP!!!! Thanks Dan..
