You might get lucky, if you don't have major rust issues, the fender bolts will back out without breaking. A little "heat" might be required, but don't start any fires!!! I've pulled fenders off three vehicles and only on my 53 did I break half the bolts. I was able to weld a bolt onto the broken bolt and remove most of them. The rest had to be drilled and tapped. Just clean the bolt heads off so you can get a good grip, and maybe tighten first then back off the bolt? It's difficult to get any PB blaster onto the bolts unless you drill access holes?
