Door Top Seals - Yes/No?

[Super_Dave]

So, we are having a debate at the moment, as to whether or not the '73-'74 Squares used a Top Seal on the doors.

My '74 didn't have any when I purchased it used. . .
Some suppliers sell them for the '74 and some do not. . .
I looked at a pair of replacement doors to buy for future needs and they had the seals. . .

So I say they were supposed to be on the truck and maybe mine were removed at some point for some reason. Why else would manufacturers make them for a '74 if they were not supposed to be used?
