One last thing, if someone has a '85 Ironman, can you post a Close-up pic of the OEM rear derailleur shot from behind. Alrighty then Ironkids, hang in there.
I had to source those screws for my 85 Ironman (I went the drilled-out cable stop / bar end shifter route).
Worse comes to worse, you can source those screws from Loose Screws. Don't go through their website; their eBay store has free shipping.

If you don't need the flange on these, just put them upside down in a vice and tap with a hammer to remove the screw,
