Well, it doesn't look good Tony. All my other LA pad partial VIN stamps in that same time frame have different fonts and are spaced much different than what you have. Granted, I don't have a ton, so I'll let Kurt or one of the other guys comment.
Get the casting date anyway, and go ahead and post a picture of the windows sticker. And get a picture of the suffix code too.
I see that the car is all over the internet (example
HERE), so see if you can also get a picture of the rear axle date and the transmission code.
