None of those little weenies fit my cup. I use a 32oz big gulp, vintage 1993, and I used to have a QT cup holder for it, but it finally bit the dust. On a gen I, you could slip the underseat lip of the holder under the front bottom edge of the lower center console, and it sat over the little depression in the tunnel console. Lip broke off. Plan to replace that one with a new holder made from sch40 pvc and some aluminum sheet stock, maybe .120 thick. I'm shopping for another gen1 now to fit it to...
