Tom,  Bill Maddox has a source of an oil door kit that we used and modified.  It also included a release button that was located inside the door frame, cable, tubing, etc.  I can’t remember who it was.  If you don’t get any other, more specific, replies try contacting him.  Joe Trepicone

I wasn’t following the pic posting conversation very closely.  If the images don’t appear please contact me directly.
