New radiator, world of difference.

Good deal, I don't know if I would have dealt with that issue for years tho. What is your fan set up now?

Still got the mechanical 6 Blade solid fan (off a 340 Duster with A/C) and a small 10" Pusher Fan in front. I removed all of the seals and rubber that I had installed before (I had glued rubber between the core support and old radiator to seal it to the core to direct as much airflow as possible through it)

I have other 4WD's (broke down at the moment though) and my '84 D50 was miserable to drive in the summer anyway without A/C, the heat that rolled through the firewall and floor turned that truck into an oven in the summer. Yay, I can finally put the Condenser back in and hook the A/C back up!
