1956 GM BOP panel interchange help

In brief, I have a 56 olds 88 2 dr. need patch in front of rear wheel to about 1' past the door jam on the rocker.

Do buicks and pontiacs share the same contours and dimensions in that area? Obviously 4 dr will be dif than 2 drs and models alike.

 

Sad to say but, no!
You will need to fabricate something, or find an old NOSR repair panel.
Those panels show up on ebay sometimes.
Also there are a few Olds only suppliers in Hemmings.
Good Luck!

 

Small buick like special and century may work. bigger buicks are different.
