I got a 10-69 build date also but don't know the day. I only have the original vin # from the old door that was replaced. They must be close though.
I don't know how much help this will be, but:
My LA built R/T has a build date of 10/23 & the VIN number is 114710, the door is stickered with a 10-69 date.
If your VIN is 109592 - our cars are 5,118 builds apart. I heard somewhere that LA used to average about 200 cars a day, so going through the math, your car must have been a very early Oct. build (around the 1st or 2nd).
Barry may be able to narrow that down a little closer - he was able to tell me that my car was probably built late afternoon on the 23rd!
