Another leaf spring question

Well @72bluNblu @RustyRatRod & @junkyardhero confirmed what I was thinking - I have a new mount on the way and I'm going to be visiting with a buddy who does fabrication work for a restoration shop to see if he'll help out with the welding.

On a related question - do you think it would be worth it to start working on peeling off all the undercoating on the car to look for any other bad spots while at it? I've visually inspected and knocked around on everything and the only spots that look questionable are this one and a couple of others around bolt holes. But I guess who knows what someone years ago coated over rather than repairing. I suppose I could spend the next week under the car cleaning everything up and have them fix whatever else is found at that point - I just don't look forward to spending that much time on a crawler - but it is what it is I suppose. What would you guys do?
