What other gm cars use the same frame as a 1979 Chevy elcamino?
the 1979 el camino shares the frame with the 79 Malibu wagon and Malibu classic.I believe you can also use the 80 to 87 frame under the 79, but you cannot use the 78 frame under a 79 as it is a few inches longer. this is because Chevy used the Impala frame through 78 and then in 79 they switched to the Malibu frame.
