Gotcha, LE and GXE have them. I dont know if any other years have them, but I'll keep an eye out and post.
Thanks for the additional pics. I want to see how that very center hinge is mounted, but you'd have to take out the seat to see the mounting. I didn't cut anything off my car though so I'll be okay to mount up just about anything, guessing its a plate like the one I cut out of the B14 I pulled my hinge from.Tomorrow I'm going to cut up the B14 plastic that I have just to get something over the side hinges and secure them some more, the plastic acts as a spacer between the hinge and the wheel-well.
I'll make a write-up about it and add it to the thread about the conversion if I can find one, hopefully in gray or blue, that tan would be kinda nasty on the color scheme of an SE-R
