I've been looking all over (in town and online), and I can't find a cup holder for my 85 fleetwood. I am trying to find the one that goes over the transmission hump and has the sides that go way down (rather than the slight curve most have).

Kind of like these:

but with the deeper curve that'll fit the tranny hump better. With two cup holders and some minor storage.

Has ANYONE seen these around? I've checked wal-mart, napa, advance, harbor freight, no one seems to have these.

Funny you mentioned this.
I was in Mills Fleet today looking for the same thing.
Just like you, all I saw was similar like in your pics.
No deep curved holders. Only slightly curved ones with
studs on the bottom to help hold it in place.
I bought one and was hoping to find a better one and
just return the one I purchased today.
Anyway, I guess it will work as long as you don't
drive too agressively with drinks in there.

I'm thinking of possibly making a DIY cup holder/organizer. I have the next two days off, and I just got paid, so I'll see if anything gets done.

How about replacing the center arm rest with a newer one that opens and has a 2 cup holder built in? I did this on my 85 Coupe DeVille. I think mine came from a 90 sedan.

Here is a thought. I took a few measurements and made a Walnut base for the aftermarket cup holder. Some red oak stain and polyurethane and it turned out pretty good. The key is to start with a piece of poster board and keep adjusting the curve until it fits the hump. Transfer that to your wood and your set.
