Josh -- is the FAN too thick?
If so. SPAL makes each size in different thicknesses. The thinner they are the less air they move - but if your system is working well... and you only need to go from say a fan that moves 2700CFM down to a size that will fit - and it moves 2250CFM... that might still cool fine. I have STAGGERED fans on the Mad -- because of clearance -- so just the one fan is a bit thinner and I have the SPAL PWM use the bigger fan as fan #1 and the fan that moves slightly less air as fan #2.
That pan hanging down like that --- nasty accident waiting to happen! Ask me how I know. LOL Had a 66 Vette that I did that too.. on the WAY to get a skid plate made - I scooped up part of the street. It won't buff out.
