Hi there, thank you for your welcome reply!
For the cabin filter I had to seal the inlet compartment, then I glued foam around a standard 1999-20?? grand cherokee cabin filter to make sort of a sealing gasket, made a drip screen, attached 2 plastic radiator mounting "brackets" http://www.summitracing.com/parts/der-13001/overview/ to the filter, inserted the filter inside the inlet compartment and pulled/fixed it to the drip screen with the 2 mounting "brackets". Hope this makes sense, I'll take some pics wen I change the cabin filter.
I know the 17" R/T wheels, but I prefer the 16" wheels, I'm a little old school
I did delete the fan clutch system on my 92 Jeep Cherokee (in the attached pic), but not sure yet if I will do it on the Durango, I will start a tread in the tech forum, need some information to figure out how the O.E. aux fan fits and can be added.
