I'm sure there is an electronics store within reasonable distance from you.
The issue I'd be concerned about is depending on HOW it blew up, you could have more of a mess than you initially though. Still, caps are pretty cheap and if you can do a halfway decent solder job, you're golden.
I'd prefer to match like for like caps, I don't like going to a higher voltage. I am in a similar situation. I'm replacing 2 pairs of identical caps in a switch of mine. I just need to get a chance to head out to the place that has the stuff. I'd be hesitant picking up whatever part you needed IF I didn't have a picture of it to refer to and show them to say "THIS IS WHAT I AM AFTER".
I find this works best.
