New here. Digging up this old thread because this actually worked like a charm for me! Thanks so much for giving me the courage to try it! After spending a lot of time over multiple days replacing the drip pan support rails which had rusted out and broken (along with those screws), I noticed that there wasn't much left of the restraining bolt inside the cook box so I needed to tackle that as well. Used the dremel to cut off the rusted broken end of the bolt then tapped it out. It didn't show signs of loosening with each tap but then on the 8th or 9th attempt the bolt popped right out. What a relief! Now off to the box store to pick up a replacement cook box restraining bolt. Does anyone know the size of the OG bolt? Grill is an older Spirit E-310 with horizontal burners and control knobs on the side. After I get the cook box reattached she's getting new burners, ignitor and thermometer. Have all of those just waiting to be installed. Thanks!
