Need help sourcing a radiator for a 76 aspen
 

So I've been having trouble sourcing a radiator for my 76 aspen. It's a weird core that's only 18 and some odd inches wide and 18 some inches tall. Cant seem to find it anywhere.THE PARTS NUMBER IS 3869991 Any help or information you guys can give me would definitely be appreciated. Thank you guys.

Google is your friend!

First off, are you sure that’s the stock and/or stock size for the car? Everything I’ve found isn’t 18x18, it seems, as you’ve already encountered. A few I’ve come up with below.
