yes this would work in a 2 door, 4 door or wagon, Universal. This is the std heater core, There is a deluxe heater core that has its own similar but unique under hood fiberglass housing. Essentially it has a longer housing shield that blocks more of the open air plenum of the fiberglass housing and by doing that it puts out more heat.
I did this in my convertible as I do drive it occasionally in the winter. and just wanted more heat output.
I will dig up the link to my restoration to show people what I mean…
