guys, i need some help locating vin numbers for a 1955 buick that is missing the vin tag off the left body cowl in front of left door.it really makes it a pain when these tags are missing, was hoping buick stamped it somewhere on the frame like other makes of vehicles i have owned in the past, thanks!
The number may be taken off the engine, stamped onto the block on a tab , left side of the engine, between the two center exhaust manifold ports. Number should end in a 6 for the Century series
https://www.teambuick.com/reference/years/55.php NAILHEAD Codes 'til '58 The engine serial number is stamped on a machined surface on the top outer edge of the left cylinder bank, between the middle branches of the exhaust manifold. The last digit of the engine serial number is 4 for Series 40, 5 for Series 50, 6 for Series 60, 7 for Series 70. According to some sources, a 100 suffix is used for the Series 100 Skylark of 1954. A stamped 1/4" long dash after the production code number indicates a .010" O.S. production engine. It is not unusual to find the letter I used in place of the number 1 in the id numbers (this makes alteration more difficult). In some cases the letter I is intended, as in the case of year identifier character for 62. The VIN is the same as the engine serial number for 1957 to 64. http://www.buickheritagealliance.org/index.php/restoration/identify/locate_numbers
I have found them stamped as far forward as the frame horn on the drivers side. Usually requires fender removal when they are that far forward.
Look on the top of the rear frame behind the axle crossmember. That's where I found the number on my 49 Buick frame. Passenger side.
