    I made a hold-down bar to keep my AC shroud from dancing while I'm towing it. I got the bends exactly where I want them, and just need to drill out the holes, put in the bolts. after I repair the cracks in the shroud itself. Unfortunately the 2 screws in the front won't budge, but the ones in the back turn freely. Hence my really stupid/newbie question: The bolts in the front of the unit loosen/tighten the same as the ones in the back, right? Righty-tighty, left-loosey? Should I spray them with some PB Blaster?
    It's almost like the previous owners torqued the H*LL out of the screws, or used some glue in the hope that it would stop the shroud from moving. I just don't want to strip out the screws, so I figured I'd ask.

    I've had some luck clamping Vise Grip pliers on screw heads to get them out.

    Thank you, Twisty. I'll give that a try today. I guess if I can't get them to turn, I can go buy a screw extracting kit, like you'd use for broken/stripped screws.

    Before the extractor kits became popular one would take a drill bit the size of the screw head and "drill the head off" then after the shroud is out of the way, vise grips and sauce of choice (pb/wd-40) . Good luck.

    Thank you, Arffch! I never thought of that! That'll make it a lot easier. I just tried to get a good grip on the screw head, and it just won't budge.

    I finally was able to remove all four bolts. The front left bolt's thread in connector (or whatever it's real name is) was loose, so as I turned the bolt the entire assembly would move. It was a good thing that the corner plastic was completely broken off, so I could remove the cover. I had to take apart the top and side of the metal housing of the ac unit, to get the connector and bolt off. I put a bolt with the threads poking up, so I could put washers, lock washers and nuts on it, to hold the shroud on. I then fixed the shroud with some fiber glass adhesive pads and 2 part epoxy.
    It's not the prettiest fix, but it's good enough. You don't see most of the patchwork from the ground. At least now, when I eventually replace the shroud, it'll be a piece of cake. I also put some screening across the vents, there were 2 wasp nests in there, and I'm hoping this will keep them out.
