Parts for 95 Thor Columbus

[grizzz]

I have a 95 Thor Columbus and need to find the water reservoir for the windshield wiper. Parts stores have generic and want to drill to mount would rather get OE if I can.
Also the wing broke off on the heater/air cond control so I need to find one of those also.
Any clues on how to remove install the controls would help along with a place to get the parts. I have tried to go to Thor but all I get is sales.

Have you tried Goggling and asking that?
It never ceases to amaze me what I can find out from Google.
