Best place to buy choke switch and cable?
 

I have an 85 rx7 gsl completely stock. I've been having a lot of trouble starting it and ended up taking to a mechanic. I was told it can be started, but that it needs a new choke switch and cable. So far I have come up short looking on the Internet and any help would be greatly appreciated.

Also if you need any additional information I'll try my best to give it to you. I'm inexperienced with cars and especially rx7s so it might be a little difficult.
