SOLD SOLD SOLD - THANKS 914WORLD!
I've got a front bumper top rubber that looks to be in pretty good shape, part number 914 503 023 10. Has all 5 studs with full threads. There are no gouges in it and it fit perfect on my '74. Right in the center appears to be 2 small bumps. I'm switching to fiberglass so this really isn't needed anymore by me. If you're interested, PM me and I can send some more pics.
I know these are NLA and someone is making some nice repros for $300 so its tough to gauge what a reasonable price would be, so I'll put it out here for you all to decide.
EDIT: Thanks to all for your feedback. Let's say $175 OBO. Buyer pays shipping.
I can't tell what the 2 small bumps just off center are, but if that's a typical spot where internal rust starts, that's probably what they are.
I'm located smack dab in the middle of NY state for those available for local pick-up. Shipping is possible as well.
