64/65 Barracuda factory Options question

You have an interesting and very nicely optioned 65 Barracuda.
A couple of thing came to my mind reading your paper work.
(1) 2.94:1 rear end ratio was optional with 4 speed....3:23 was standard
(2) I thought, even in 1965, federal regulations mandated a window sticker to be included in a new car sale. Was this a new car sale? Or was this a Chrysler rep car sold by the dealer, which may or may not have included a window sticker? Usually a rep car sold by the dealer has the car mileage stated on the sale record.
(3) I see nothing to explain how or why the sway bar is present unless this option was lost with the missing window sticker. The car may have had the 325 option Performance Group from the factory. If this is correct, your car should have HD torsion bars (blue paint blob on the bar and/or 892/893 if you have the buildsheet ), HD rear springs and power brakes.
Note: the torsion paint blob is usually visible after wiping it clean along its length.
(4) I would like to see picture of the fender tag and buildsheet if they are available and perhaps we can unravel your mystery. The answer likely is contained in the buildsheet or IBM punch card. The punch card may be available from Chrysler Historical Society for a fee.
