Does this mean it took a lot longer to build my car?

The VIN is assigned when the order is placed I am pretty sure , not when the car finally hits the assembly line.

Are the 2 build dates you mention for cars built at the same plant ?? Same year ???

Different plants and different model cars but the same year cars, both are 69 models

1969 a & b-body assembly plants:
"A" - Lynch Rd. Detroit, MI built ~215,000 cars - R & W b-body lines
"B" - Hamtramck, MI built ~355,000 cars - a-bodies & Chargers
"E" - Los Angeles, CA built ~72,000 cars - a-body and R & W b-body lines
"G" - St. Louis, MO built ~310,000 cars - R, W & X b-body lines
"R" - Windsor, ONT built 172,000+ cars - a-body & c-body

St. Louis plant WM2xx9G240xxx w/SPD 326
Hamtramck plant LS23M9A344xxx w/SPD 329 (best guess w/o more info, your car was actually assembled a week later on or about Friday, 4/4/69)
What's the date on your K-frame and/or your engine's EAD? What's the "SEQUENCE #" upper left of your b'cast sheet?

The 1969 A12 & A13 "program" cars had "make believe" SPD dates & their VINs were not assigned until the plant actually scheduled its build. IMO your car didn't take any longer to build.

I have a copy of a sheet from:
LS23H9B350342 SPD 411 & SEQUENCE NUMBER 1 171197
LS23M9B344xxx SPD 329 & SEQUENCE NUMBER 1 173150

Based on the b'cast sheet's sequence number your car was started ~2000 cars (only a few days) after the 383 GTS. I just do NOT have enough info to figure if that's later than my 4/4/69 "guesstimate" or the above 383 GTS was a week early.

K-frame date would help if available.

The LS23H9B350342 sheet was in LS23M9B341723 another 329 SPD 440 Dart GTS.

I can get the k frame info tomorrow

That's correct, 0909 1 would make more sense but it is what it is. Was/is the car pretty unmolested (for a 440 Dart), lots of parts can be changed in 45 years.

I'm curious as to where to look at my 1969 GTS K member for a date code, it's a H code car. Mine is not numbers matching, way to many owners and way to many years of racing it

---

Look on the front face of the K frame that faces the bumper

K frame dates are often VERY difficult to read due to the thin stampings being buried in rust paint and grime. You usually need to strip the area to clean bare metal to make them out

Thanks to both of you for the help This car was hit pretty hard on the left front before I took it in trade with no motor or trans. It does have a early A body 383 K member in it still but I'm curious if it is the original one or not I'll look at it tomorrow in the light, it is storming here now and I don't want to push the car out of the garage in the rain and hail
