[jeffs 89 cutlass salon]

I am going to a yard near me, to grab another A/C heater box for my 78 cutlass salon. I did locate another 78 like mine, and I also found what appears to be
a 78-80 malibu, with the entire front clip,and engine gone.

what I want to know, is would the box from that malibu fit My 78 cutlass salon?
as this one would be much easier to remove

if not, I will grab the one out of the other car like Mine
