1978 K5, 350, SM465. Nothing crazy done to the motor, just a cam. The starter keeps moving away from the flywheel, no matter how tight I get the bolts. I can move it back and it starts fine for a while, but after 10-15 starts (sometimes less, sometimes more) I have to get under the truck and loosen the starter bolts and move it closer to the flywheel again. It's at the point where it's starting to chew up the flywheel. Any suggestions on what to do to prevent this?
