Anyone know where to get Peterbilt parts online?

I was looking at replacing a rocker switch on on my 07 386. One of the ones that says spare on it I was using for my oversize strobe lights burned out and I was unable to fix it internally.
Peterbilt wants $75 bucks for a new one, which I think is unreasonable. I found peterbiltparts.com but they want $54 for a blank switch.
Yes I know I can buy a cheap rocker switch at autozone or whatever. But I really want one that matches all the others.
So is there any one out there that knows where I can get parts online for a more reasonable price?

 

Yes, big rig chrome only has the chrome rockers. They only have the rocker part and not the whole switch. The same goes for 2 other chrome shops I stopped in. They don't sell the whole switch assembly. Only the chrome rocker. I need the whole complete switch assembly.
And Ebay didn't have them either.

 

I also need a power mirror switch for the same truck but can't get one from peterbilt because my vin doesn't have a power mirror, and that's the only way they can find parts for the #### thing. Which really makes me mad that they can't look up a part by a parts diagram instead of by vin #.

 

Yeah but $75 bucks for a stupid plastic switch is down right rape.

 

Maaaaan! Your really not helping me here. LOL!
