1967 Barracuda fastback fender tag deciphering

This is what me thinks at this point.

SPD is definitely Scheduled Production Date.
118 is definitely January 18, 1967.

Customer ordered cars have 691 on the IBM card and the broadcast sheet, and u1 on the fender tag.

The 67 conv above has neither.

It was however shipped on 5/2/1967 and, according to the dealer, delivered to the dealer on 5/10/1967. Not sold by them, delivered to them.

6/10/1967 it was bought, based on the dealer warranty certificate dated that day, and the Certicard punched with 6.67 as the date, both with the same owner's name.
My understanding is Certicards are supposed to have Month.Day.Year, some do some don't.

My theory is, for whatever reason, if a car was customer ordered, or ordered by a dealer (or sent to a dealer) after 1/18/1967, it was Designated Line 2 Build.

I'm thinking a loaded up 1st year bb 4 speed conv was either built by the factory and sent out to lucky dealers, or ordered by dealers.
And in this configuration, considering late model 67 launch, bb availability, conv too, it probably was an 'early' version.

There are multiple dealer order codes that would be on the IBM card/broadcast/fender tag, and this car has none of them.

That's all I got.

Only other is code 702, which equals BID.
I thought I knew what BID stands for, probably did at one point, but it's the only code that would fit M2, possibly, but fyi that conv doesn't have it.
