Thanks everyone great advice and comments. I really don’t want to do any cutting and what’s in place does feel very solid. So I’ll take from some of your advice and run another hanger bar across the top of the current one and use some hose clamps to help add a little support. Then I’ll use a washer and nut on the end of the bolts just in case since there is limited thread for the bolts to grab on those tabs. I feel pretty comfortable with that. Thanks again everyone!
