Mr. X-Frame, do you know about other frames, too?

On mid fifties Mopar cars, is convertible frame beefed up more than two-door haardtop (no B-pillar)?

[X-Frame]

Yes, all Mopar convertibles up to 1959 had an X brace and the steel is thicker than the side rails. (went unibody in 1960)

Imperial models continued with a seperate frame until 1967 when it went unibody.

Thank you sir. Do you have diagram of the ragtop frame?

[X-Frame]

Here are a couple of a 1957 DeSoto Adventurer Convertible one of which you can see the thickness of the X beam.

As far as style, the "mid 1950s" design ran from 1957-1959. The 1953-1954 model was different and depending on brand, the 1955-1956 are either the same or slightly different.

Which car are you working on - interested in and I may be able to zero in better?

Thanks very much for your time, 1956 Desoto

Thanks very much for your time, 1956 Desoto

The 1956 frame is different than the 1957 but same basic concept. I will look for a 1956 chassis to post.
