nice job on the radiator install ! up you may want to consider a way to panel off the area above the radiator to the top of the grille shell similar to the way the bottom of the shell meets the bottom of the radiator. this way, a lot more air flow will be forced through the radiator core instead of being "washed over" and bypassing the radiator altogether. i believe this would help cooling immensely, and be a big assist to the small confines of the grille shell width wise.
