67 dart dash frame

67 68 and 69 are all different
67 has a round knob radio and no holes drilled for a Vin tag.
68 has a bunch of holes drilled for the lower pads, and holes for dash vin.
69 has Vin holes and a thumb wheel radio, making it completely different.

Yes extra holes can be welded...but the metal is thin, easily warped, and would require more work.
