68 skylark convert frame swap options

[buickblimp]

anyone know what frame (if any) is the same as a 1968 Buick Skylark convertible? Ive got one with rust in the rear,just wondering if any other models will fit before I start building one. Is the 68 Skylark 4 door the same? Thanks for any info

Buick Special '68 2Dr., Conv.
Buick Special '69 2Dr., exc. GS400 H.T.
Buick Special '70 2Dr., Conv.
Buick Sepcial '71-'72 2 Dr., exc. 8-455
Chevelle '68-'70 2 Dr. exc. Pickup
Chevelle -71-'72 2 Dr., H.T. & Conv.
Olds F85 '68 2 Dr., Conv.
Olds F85 '69 2 Dr.
Olds F85 '70 2 Dr., Conv.
Olds F85 '70-'72 2 Dr.
Tempest '68 2 Dr., Conv.
Tempest '69 2 Dr.
Tempest '70 2 Dr., Sdn.
Tempest '70 2 Dr., H. T., exc 8-455
Tempest '70 2 Dr., Conv., exc 8-455
Tempest '71-'72 2 Dr., exc. 8-455

I would suggest that the "exc. 8-455" frames will fit except that there may be extra body mounts and that they are boxed, stiffer frames than original.

the 4 door frames are longer.
You will need the 2 door frame from 68-72 Skylark or the others mentioned above. The convertible frame is boxed in the center section to help it with strength, so you either need a convertible frame to replace yours, or you can box in the center section yourself.
