Any pictures of this Crack? How bad is it ? Can it be repaired without removing it from the car ? It has lasted 55 plus years and your car looks great and I'm not so sure you need to replace or remove. I'm thinking repair it so it doesn't get worse. Of course just my thoughts you may disagree.
It was repaired last summer, welded in place in the car. Here are the before and after pics. Maybe it is ugly but Ok for now. I am hoping to get the car on lift this weekend and get a better look. I mentioned something is wonky with the car, so here it is....the engine sits askew with the oil filter on the passenger too close to the frame rail. Someone took a grinder and added some clearance to the frame rail so the filer would hit. I don't know what to think and claim little understanding of how everything sits.
