Just an update on the 5305 coils the bags go on the bottom with the dead coils on top and run the air lines through the top and out over to my gas tank cover behind the lid worked out perfect. Hopefully this many help others who are unsure.
What bags did you go with and did you happen to get their measurements?
Since my last reply to this thread, I've installed mine (the shorter ones) into the TJ coils. They were a perfect fit. I think they would've fit 'ok' in the 5305s, but there would've been too much space above the bag inside the coil. The 5305s didn't work out for me for what I needed and with how I'm trying to use the bags, I can't have any space above the bag. Air Lift may offer a bag of the same diameter but an inch or so taller that would be perfect for the 5305.
Oh, I also routed the hoses up through the coil pocket, over the cross member, etc.
