Nope. You're going to have to show it or explain it.
I used the Robert West Survey of 1964. Measuring from the SN to the limo, I get a lateral angle of 9 degrees. I don't know what you mean by "reconcile the 2". What exactly is there to reconcile?
How do you know that survey map is to scale? Let's give it the benefit of the doubt. You need to determine where the limo was relative to the Z-film to sync with the shots. All that is a bit iffy, but I will give you the BOTD again and say your angles might be ok.
If so, then put the limo with occupants into the scene and line everything up with a shot 2 inches to the right of the spine at T1 and out the throat at C7, then into the right side of Connally, into his wrist, then his thigh then ending up on the wrong stretcher.
Use my laser experiment for a re-enactment for JFK and Connally and make me eat crow, I dare you!
