    I have a GS hood on my skylark and the other day I was doing some work on it and thought I should finally add the GS breather. So off to the parts area and I grab the plastic pieces and a bag of screws to finish up my breather. Well, it turns out who ever took the top and bottom plastic pieces off years ago broke about half the screws off. Does anyone have any idea or have ever taken rusty broken screws out of the plastic pieces for a 70-72 style breather?

    Maybe try grinding a screwdriver slot into each broken screw with a Dremel cutoff disc. Shoot some PB blaster or Liquid Wrench on them to penetrate while warm from the slot grinding.
    Or grind ends flat to be able to drill a centered hole into screw and eazy-out it. It may come out easy just from the drilling heat.

    I used to use a left hand drill bit all the time on broken off screws in metal.

    Good luck, maybe others have ideas.

    Hard to see, but looks like someone may have epoxied or jb welded the screws in.
    When you finally get them out, you can cut and insert short 1/2" long pieces of zip ties to get the screws to bite again in case the holes are wallowed out. Possibly insert a cut off plastic wall anchor also.

    X2 on what Mart said. If you do, have to go bigger, you can use thread inserts. Patience is what you need and a drill press or a Bridgeport so you go down in straight.

    It does look like epoxy but its just penetrating oil on them.
    My plan is but haven't done yet is grind them flat, center punch and left hand drill them.
    My go to on any broken bolts is always weld a nut to them and out they come but I don't think the plastic will like the heat.
    I will let you know how I make out when I get around to it.

    Pull the spring loaded pin and use the broken stud for a guide. Go in 1/4" and use vise grips to unscrew broken stud. Pat

    I agree with AR, milling machine would be best Hopefully someone close to you has one or send it to me.

    Its friggin' plastic. Use the tool above, and back cut it 1/4 inch. Take a soldering iron and make the stuff HOT. Mini vise grips will bite it and back them out. You cant overthink this stuff. Send them here and theyll go back out the same day. The steel screws rusted away and failed. Thats the moral to the story.
