ok this is a newbie /non-mechanic question..

after an air cleaner base for this one - the base on there now is a something hacked-up/cut-down from I don't know what and does not seal at all where bottom of air filter meets base. Was thinking of getting another unit with similar drop and just using the new base.. just barely clears coil using a 1/2" spacer..101_3023.JPG
