Xcntruck and allenfeyhe both did super nice cages with the tube through the dash. But there custome built cages. The aftermarket ones will hug the dash but not as tight as your gona want.
I just built myself a front hoop out of stainless tubing and used plate steel for the lower legs. Its super sleek and super tight. nothing sticks out any further than the stock dash. My tubes are within 3/4" of my viewfinder windshield frame. My lower plate legs bolt to the side firewall and the dash and its super super stiff...and I don't even have the 4 floor plate bolts in yet! My front part of my cage is just like a Spyder cage is built prettymuch.
So answer to the question is if you want it tight then you gota make it your self and go through the dash. If your not as picky as me then anybodys cage will work well for you.
Id throw up some pics but everybody shot my idea down when I brought it up a few month ago. Instead of helping me with a design and throwing out some pointers to me they said im a idiot and there is no way a plate steel lower front leg is gona work
But its done and its sweet!
