Hmm.. maybe a net would just be less hassle. Or, I may see if some later model hardware will work better. I know GM used a "cup" style pivot point, with the same type of side latches... no floor hinges. So, since the TG isn't a concern, (making a flow through w/ sqaure tube and expanded metal) then maybe I can make it work by notching the new agte where it's needed to make the hardware from something else work.
I'll have to do some looking around. Thanks for the info so far.
