Fender tag info

Also, since your car is a "package", a 70 Swinger 340, many items came standard (incl. rallye dash), that were optional or n/a in other models.

Further options would be found on the broadcast sheet, which is found inside the car. If the interior is orig., pull the bottom of the back sheet and see if its there. Other locs include under front seat, under carpet, above glovebox insert under dash.

Nice find
