I have a 71 Cutlass convertible and I am in need of a chassis for this car. I live in Missouri. Does anyone know were I can get a boxed frame for my car. I have been looking online and have not found anything, please help.

 

Frame itself is the same as any A body - Chevelle, Skylark, Tempest convert.

 

Hardtop & convertible frame are the same except for the part under the rocker panels which is boxed in. 507olds has/had a set of the boxed portion of the frame from a convertible. Any '70-'72 G.M. A body will work if you weld in the boxed portion, & maybe '68 & '69?
