I have got a few items from Rock Auto. I'm 90% satisfied. Most are great parts at a great price. My last item is the fuel tank filler neck. This was to be an exact fit part. I did replace the old one and it did fit. When I went to put the gas cap on, it didn't fit. The original is a twist and click type. The new filler neck accepts the threaded type gas cap. I'm finding it difficult to find the correct gas cap on their site. I also can't get a human through customer service to call me.
