Thought I’d share my hack so I’m putting in the 4 core radiator but everything is under tension as I try to put top plate back on. So after a good amount of frustration I decided to cut out 3/4” out of the top plate both sides so radiator can sit in a natural position. Simple fix for anyone not looking for originality and wanting things to fit smoothly. I still have to finish welding grinding and filling in 2 spot on each side, but dam it goes together so easily now. I’ll upload finished product pics when I’m done. Enjoy
