My brother-in-law owns a pre98 and he said he built a new cupholder out of plywood.

From what I understand, you no longer fold it up, it's out permanently. I have not seen it, so I can't comment on it, but it sounded kinda junky to me. However, he builds lots of stuff like that, so it may be really nice.
Doubt if that helps you any, tho... sorry.
