No problem with the hijack. I'm glad this may be helping someone else. I'm not sure what to think about the lack of markings. I agree with the welds and the metal. It looks like 304 stainless which SSI uses. The driver side also has only two holes. SSI provides a tool for this reason since a pipe runs through where a third hole would be. Maybe some others will chime in since I'm not an expert after what happened to me.
In my case, the seller still refuses a refund dispite the fact SSI has provided me proof what I bought is not SSI. Pay Pal was no help since they only guarantee the item is as advertised if purchased on Ebay. My credit card company is looking into the matter as I'm about to send all of my documenation to them. I'm hoping for the best.
