Hot Rods Frame Vin 52 buick

I have a 1952 buick special that is mine vin tag on door. Does anyone know the frame location?

 

Vin tag should be on the driver's door pillar.
Frame number is stamped on the driver side frame rail near the left front tire.

 

My 53 Cad has the serial # on the p***enger frame rail above upper control arm. easy to see, open the hood and look .

 

On Buicks look on the top of the p***enger side of the rear frame behind the spring pockets and ahead of the bumper.
