I recently purchased an 1988 vmax with supertrapps containing 10 4inch discs. I bought some great looking open endcaps for the mufflers, though when i was trying to remove the screws that hold the discs, they start coming out fine, get half way and then they look stripped and now just keep turning. Is there any easy way to get these things out? I've tried 5 screws and they all do the same (there's 6 screws each muffler). Removing the muffler isn't really an option as it's been joined welded to the rest of the pipe..
Also there's a bolt underneath, what does that do (guessing holds the baffles)?
Any help would be appreciated.
