Drop down center arm rest

Greetings. I'm kind of new to this site. Got here via local hot rod friend of mine, anyway, I'm rebuilding my t-bucket this winter...longer body. Tired of driving with my knees under my chin...okay it's not that bad, but bad enough.

Anyway, I would like to incorporate a center arm rest within my new seat back which I don't have started yet, but need to get some ideas. Looking for something narrow. Be great if it had a cup holder incorporated into it as well. Strange how we've come to depend on cup holders. Well better than the way we used to hold cups when I was much younger. :LOL:

Anyway, if I could get some input that would be really great. I will prolly be back bending every one's ear later on as well with more interior questions. Now mind you the interior of a bucket is not much, but you also have to realize we have to make the most out of what little space we have. :-)

Thank you in advance.
