Not sure if would be interested in this kind of vent...
It's one big panel and there are few different brands - I went with Hyline Offroad

(There's another pic of my TJ on their home page - green TJ heading into a ditch with water in the bottom).
I've had the vent panel for 3.5 years - it made absolutely no difference to running temps but it's great at venting or dispersing 'heat-soak'.
The heat coming out of the vents is unbelievable.
Was also handy for a couple of other reasons - the paint on the 97 bonnet was a bit average and it had some hail damage.
Also gives me peace of mind when I'm crawling rocks all day in 40 degree heat or long runs up North when it's even hotter
Had to carve up the bonnet to fit the vent...
On the downside, the powder coating on the vent panel was looking a bit rough after 2 years, so had it re-done.
Rear-facing vents are illegal in some States.
