putting in A.C.

You?? Put it in yourself.
I'm going to be doing the same to my 85 D150
But I'm nowhere close to Florida.
I don't know Florida geography well but I know someone in that state, a regular on this board (@CharrlieS) that would be my 1st contact for the possibility of having the needed parts. He has a few early A's still running around
I dunno if he would be close to you as I can tell by looking at a map that it is a loooooong state.
