Anyone have a good source for the correct length and high grade starter bolts for the 6.2? All Napa has is a "universal" bolt, which is about a quarter inch to long and grade 9.8. Had a snapped bolt on our 8.2 Suburban starter. Installed the Napa bolt to get it back for the Misses (her Mothers Day gift), but wondering if a correct lenght, high grade bolt is available?
