Non collapsable steering column. Solid steering shaft, and weak as hell X frame with center torque tube with drive shaft inside it. This frame ran on GM full sized cars from 1958 to 1964. The 1965 impala went back to a perimeter frame. Ask me how i know. I restored a 1960 model el camino. Basically the same car underneath as that 59 bel air. Yeah the wrap around windshields pretty cool until you realize the A pillars are pre bent into a collapsed weak point. Cool looking car to bury you in after it folds up on you in a wreck. The 55, 56, 57 chevy bel air fairs a little better due to it having a traditional ladder frame.
I think if they ran the malibu into a 72 chrysler new yorker brougham the results would have been waaaay different.
