I think Galen or maybe Dave Patik .May know of a complete originating dealer 69 charger 500 list like the daytona shippment list wing warriors put out furnished by Anthony Young to give you a idea where the car sold from .I did get a copy of all 69 charger 500s sold in NJ a while back.As to these membership lists these were done by Jim Radke and the wing warriors.And later the DSAC superbird club would have these as part of there newsletters.And later updated to cars known and condition and accounting of existing cars.I dont have alot of 69 charger 500 info around as I never owning one personally.But now of some in my area.Also was looking at the red on red AC car from Missouri city near Houston many years ago like in the 80-s .Before Randy P got it and sold to the guy in Tomball TX that has it.Anyone in TX remember this car .Newsletters and cars Ive been incontact with over the years by seeing at shows or selling parts to.Keeps me up to date.But these cars keep changing hands to stay up and current with.Join one of the 2 wingcar clubs and submitt your info .Or contact them with any info about a wingcar you might be buying.Might save you alot of grief .You say you have friends with 2 cars not submitted.But actually anyone that knows the XX29 or RM23 can add the L-440 J-426 for 69 daytona U-44 V-440-6 or R 426 hemi for superbird and applies to any collector mopar vin prefix and run it through DMV in 50 states .As we seen and heard of people getting asking to sell letters in the mail .Also all superbird daytona 500 vin numbers are pretty much known by factory paperwork as shippments for daytona and nascar lists for the superbird.These to can be run through DMV as most states have a database with no time limits on a vehicle .And as collector cars are registerd and insured with speciality car companys .That puts that into right into the DMV database.So in theory any or all of these can take place
