i have gotten many things thru eBay also. You might want to check there first.
I also have used those online junkyards, like you posted, but never heard of the one you linked to. The one i used was very good. The parts were in the exact condition that was described. I have it easy though, I have an older mustang. Mustangs parts are so easy to get for dirt cheap. There's tons of salvage yards specifically for them.
I would ask around town though. You might find what your looking for and not have to pay for shipping from an online place. The price may be cheaper online, but add the shipping cost, it sometimes pays to just get it locally.
