when it comes to blow throughs only thing the same about s10s and rangers is the idea.
measure how big you want it.
get you some accordian boot. make sure you get extra. youll have to over lap
youll need a sawzall, silicone with a gun, a dremel with a grinder wheel.
when you cut the hole, there is a brace in the middle of the back of the cab
its a whore.
cut through it. then take the grinder wheel to smooth it.
put the boot on, splice at the bottom, cut one side with 6" of extra boot cut the snaps/sides/metal clips.
COVER it all the cracks in silicone do not be greedly.
let it dry.
i do a 155

with my cut through
as a warning.
when you do it the park of the box that comes into the cab, aka the face. make sure it covers it use greatstuff for windows behind this. it will seal it.
my back glass is solid.
it will break if you tune low enough, all the mounts on mine are broken. its hanging there by the grace of god. if your goin to cut it, make it worth while.
dont forget the main thing.
Get loud.
