Anybody know what this, 3940925, emission sticker looks like????? It replaced that 397744 for 68 BB's with A/C. It's referenced in the Feb 68 service letter page 7 for the 68 BB's with A/C. Patrick, I called Osborn and they didn't have one. Its's a small detail but the decacal in an entergral part of the tune up process of these cars, see attached page 7 on Feb news letter. Can't believe this part of corvette history can't be found, hope it's not lost.
