Mine melted and curled out near the tire also, I just took some good snips and trimed off an inch or so. I think the abs plastic may be too thin at the lower edge to take the header heat.
Got my extension from Murph's. You are right, I'll need to trim mine back before it punctures my tire. I doubt if Murph will refund. It's the Connie's heat causing this. What sucks is it's ABS plastic glued to the stock fenderCheck with Murphs and see what he will do. I think he will make it right with you. He does a lot business from this site and has a good reputation.
