What Chassis does the 79 El Camino Super Sport sit on?

I believe a mailbu station wagon is the same frame.

The 78-87 Elky had a 117" wheelbase. The only frame that will fit a 5th gen Elky is one from another 5th gen Elky. The 78-87 Monte Carlo, Malibu (wagon, sedan, and coupe), Regal (wagon, sedan, and coupe), Cutlass (wagon, sedan, and coupe), and Le Mans (wagon, sedan, and coupe) all have a 108" wheelbase.

I stand corrected :P

Dang, that makes things a little tuffer then.
