I was told they will not fit therefore not interchangeable, but then I have others saying they will... On E-bay people are selling the 50 Chevy and listing it for a 50 Olds. They look identical, but from my understanding there is something off that makes it not fit, any opinions? OR has anyone tried fitting the two either into an Olds or an Olds into a Chevy fender well?

 

Check with Fender Skirt Depot they should be able to tell you if they are the same.

 

I know the doors off a Chevy will work.We did and worked. I think the battery box is different.
