I used the one from www.ClassicParts.com stock code #68-009 about $40. The other option is Grainger if you take your old one in they can usually match it. This swap requires a bit of modification. The orginal fan needs to be drilled out. You have to massage the mountings and trim the motor bolts. With a replacement motor you will also need to run a ground connection to the firewall. Mine works great, here are some after pictures.
