I've yet to see a 1971 Buick Skylark with a 434 starting VIN. I've seen 433 and 444. Who has a 1971 434 Skylark, and what is the complete VIN including body style (serial number not needed)? Charts out there state that 434 is a valid 1971 Buick Skylark VIN (maybe sportwagen or post car???), and I'm trying to confirm or deny. Thanks!
Marco, SportWagon's were VIN'd as follows: 43436. Skylarks were only 433 and 444, as you stated. GS's were 43437. HTH
Thanks Randy, but I believe your car is a GS, not a Skylark. Brad - Now we can be sure the chart is incorrectly identifing Skylark 350s with model 434 for the 1971 model year - Thanks! :TU:
