Slant 6 K-Frame = LOTS of Clearance

@70Sbird What Radiator setup is that? I'm on the hunt for one now and don't want to run a stock plastic rad for a late model car.
I used a Northern Radiator # 205199 and their fan/shroud assembly #Z40112. I'm happy with the fit and appearance, it seems like a well built unit. I bought it from Yogi's and the whole assembly was was around $625.
