My speedo hasnt worked since I bought it, Does anyone know where one can be had for cheap? Or how to fix it?
Speedo Cable

Mine didn't work either. So I found someone parting out a supra and bought both the lower and upper arm off of them. Except that still didn't fix the problem. The speedo drive gear was bad. So if you pull off your speedo cables and find that they still spin fine, or you find that it still doesn't work when you change the speedo cable, now you know what the problem is.
I had the same issue and can tell you to use the "mechanic's rule for troubleshooting."
Go with the cheapest part first...
The nylon gear cost me about $25 a few years back... however, I spent the money and went thru the trouble (PITA) of changing the upper cable, then the lower cable, etc, etc... The gear takes about 5 minutes to change and is also easy to check.
Pull it off and look and see if any of the teeth are wore out on the gear. Be ready to plug the hole w/a small clean rag/towel, so that you don't lose all your tranny fluid, while you check.

My speedo needle bounces up and down from about 0-25 mph and then moves smoothly after that at higher speeds. Any diagnosis?
Yeah, the cable is not lubricating right. Some guy wrote an article, he said he put some oil on it (like, letting it get oil from somewhere on a higher level, overnight0, and then it worked. I don't know for how long that fix would work.
As far as oiling the cable.... easiest to just disconnect at the tranny, bring up thru the engine bay and hang it to the hood somehow. Before you do hang it, place some oil in a small baggie and put the end of the cable in it. You are not going to need much oil, but basically "rubber-band" the baggie around the cable... You'll have a little bag of oil, which when turned upside down (when you hang the cable), will allow the oil to flow downwards into the cable.
Don't use too much, 'caue you may pour it clear thru the other side, at the gage cluster. I would go as far as to remove the cluster and put a few towels on that end.
You can try from the cluster side too, but for me it got too messy and I was unable to really put the cable at an angle where I knew the the oil would flow thru. The cable does not need to be filled with oil. It will hopefully just work it's way thru, while the wire rotates inside.

I took my speedo out weeks ago, and can't seem to find one to buy. Funny thing is, now I don't know which end which, lol. What kind of oil does one need??? Engine oil? 
... or wd40 or what?
... or wd40 or what?what part of the speedo contraption usually goes first cause i hear is a popular thing for the speedo to go on these cars
