Hit your local radiator shop. Preferably one that does race radiators. I got a custom rad made up for about $250 that looks almost the same as the original harrison (except for core). I also got a custom aluminum shroud being made up. I am running a manual, however a bottom tank cooler for your automatic shouldnt be much more.
For street driving, I recommend a bottom tank cooler. For severe towing and racing, a separate cooler is recommended.
If you are looking for an electric fan, ONLY use SPAL or Tri-Pac. everything else are simply sub-par. I do not have any ties to either company, however these are the only fans that actually flow the air they claim base on actual NIST traceable testing.
