Light Bar Switch Cutting

I recently installed a switch from OTRATTW.com for my light bar but it does't fit. Any advice on cutting to make it fit properly since its made for a tacoma??

 

Where does it not fit?

 

Here's a good link, a dremel tool works well also.

I recently installed 3 of those switches in the stock slots to the left of the steering wheel. Rather than bothering with a dremel I just used a razor blade and trimmed what was required. Super easy and clean, here is a picture of the switches

 

I hsed a rasp, like a metal file but for wood, then a razor to square up the corners. You dont have to disturb the finish surface of the dash, just the ledge down in the hole.

 

Exactly^^^ I think that is the best way.
