I always use my impact wrench first. Nobody said you have to fram and blam with the impact on it until the bolt snaps. After a few hits with the impact, if that doesn't loosen it, I reach for the blue wrench (oxygen/ acetylene torch.) Get the bolt cherry red, wait 20 30 seconds, then use the impact. Almost all bolts come loose doing it this way. Edit: they now sell a mapp gas, oxygen kit torch set thats not expensive. If you want to get metal hot, you have to add oxygen. https://www.amazon.com/Oxygen-MAPP-Torch-Pressure-Meter/dp/B08H8P8K16/ref=sr_1_23?crid=E41J63F7HQRS&dib=eyJ2IjoiMSJ9.nusx8fyugYCFPAbqMCH_KN3mxUhLw-wQmcmYiEApN88MoM2G-QocnfXEitt1JFF3wVR3pYWkJQ6ufU08IB2Mx3m6QviV8j-RAKH-U-otXLszxlODTeqzqHdDPipXS9P6oZWobClDcYjtP1r1wsrYpC7K2UBXMaQp4mz0j7WxuTAJ3NRLCFuzHRN0Nh5Tq34cZK6FZD1SK0p_fyTjMUlW8KGVxMMGroqW4-pXVvXmgAvNlxTa9t_FUvjw8uuu_f9ZNB6afueyIneIflDH9qPKQlgu5J1zuS5Pbfgz_MW44GY.nYA0D2vHPddLgD0jIfw3J8AdNylCcWyfZ_kyicAVtmk&dib_tag=se&keywords=mapp+gas+oxygen+torch+kit&qid=1780888374&sprefix=mapp+gas+ox%2Caps%2C846&sr=8-23
