I have dealt with AutohausAz MANY times. If the part isnt listed, you can put in a request and they will get you a price in an hour or two. The cool thing is, when they give you the price for whatever part it is, they generate a shopping cart link so you can just add it to your cart. Definately handy if you already have an order going of 4 other parts and all you are missing is that one. The other thing I like is when you place the order, you have the option of paying by credit card or paypal or other means.
I could go on and on, but ALOT of my 92 was built from stuff from them. I dont have anything but good things to say about them...
