Rear deck holes
Here's one for the FABO brain trust. I've had my 1970 Swinger 340 for around 15 years, but just noticed these holes in the deck inner structure, but not through the trunk skin. Do all '70 Darts have them? Only Swingers? Or only Swinger 340's? I'm guessing they're for mounting the optional Go Wing. Comments and opinions, please.
