the bars actually come with six of the tabs; if you look at my cutout you can see the extra slot i had to make to fit the extra tabs through.

the good: the mounting points, amazingly, are THERE in the car already. there are four holes below the rear deck that line up perfectly for the roll bars.

the bad: you'll need pipe cutters to remove about the last four inches off the bar (including the bottom-most tab), because the bar is actually too tall to fit in with the roof in the way. ten minutes with a pipe cutter, or a hacksaw will get the job done.

the ugly: the visible tabs (rrrrr) aren't visible on the roadster because the roadster's rear deck comes up that much higher to cover them. i'm still brainstorming what to do with them. i can't move the tabs BELOW the deck because then the bars would be much lower than the seat. i may try and lower them so the tabs 'rest' on the rear deck. we'll see...
