I have a clean one. Any chance you have an extra A/B/E-body P/S 70-style bucket seat outside hinge cover (pot metal with release button)? Perhaps a trade?
I think I might just have what you need. Let me check in the am. Not sure on the button part but......I'll see what I can find and get him to fix up a button 'cause I'm sure it will be broken off already. He'll drill and tap it for you and install the button. PM me instead of the posting. That way they'll notify me.
cleared the box and the button is already fixed. So.... how do you want to do this?? Send me your address and I can send the cover. Mine is rod glaser 3175 w. Heritage Dr. Ozark, Mo. 65721 for the metal plate. Thanks, Rod
