26 inch radiator in a duster?
I have a 3 row 26" radiator that was for an e-body I bought from Paddock a couple of years ago in my 75 Duster and it fit like it was made for it. I also found out an m-body shroud fit this radiator like it was also made for it.
Heres a pic and even though it doesn't show the whole radiator it gives you an idea.
