Deluxe seat belts in front...Standard seatbelts in back...

Well, i posted pic's of my harness & sure enough, there are no extra connections for seat belt retractors with sensors.  i have no idea what i have, but it doesn't appear to be the right seatbelts. rats.

Got any photos of your belts?

no, i didn't get to the shop this weekend like i had hoped.  i will try to swing by tomorrow.  it is thirty miles from home, and thirty miles in a different direction from work.  the funny thing is, if i recall correctly (and i am not sure of anything anymore these days!   ) , is that they did latch to the shoulderbelts.  thats why i thought they were right.

Well, if they have a wired spool you can be certain they are wrong I guess, that is a start.

Ok, here are the pictures of the belts that i have, right or wrong.  maybe the numbers on the tag on the shoulder belt can point the way.

There is your answer! 

The date code is for the 247th day of 1973.
