Where do you put a cupholder?

[Oberon67]

Okay, I know, this is probably a stupid thread... but I like my coffee, and with three-on-the-tree I need both hands to drive sometimes. The obvious solution is a cupholder, but the '81 C10 I'm driving just wasn't made with a cupholder in mind.

I got on Amazon and ordered a folding jobby that mounts on a vertical surface, and I hung it on my (already crappy) dash just to the right of the bezel. I drilled a couple of 1/8th holes and mounted it with the supplied sheet metal screws.

I had looked at transmission-hump consoles, but those were awful expensive for what you got.

Thought about putting one on the door instead, but I like the dash mount better because it's handy to my right hand, and it's more secure.

What have your solutions been?
