I like the fact that Bob took the time to research this. I already knew mine was stainless steel, and anyone who thinks stainless is soft should do as suggested and that is try to drill thru a piece. It's hard, and it's strong. I would never put anything less on either of my cars. I just wanted to understand what the problem was. Thanks to Bob, I now know, and that is that. I will still monitor my pulley as I still do the Code 3 I run on the roadster. Any guess what that metal is? Stainless is used quite a bit, especially in the trucking industry. I have a lot of polished stainless on my new rig. I feel a little better now. As I stated earlier, I voluntarily left the facebook page, as I did not feel at all welcome there. A few people got under my skin very quickly. Best to move on in that case, as you know from my posts here, I don't last long taken crap from someone who hasn't been there and done that. With that said, I think we are done here. A big thanks to Bob, and others who contributed reliable information here. Thanks for posting a photo of all three Lenin. Maybe that will help others keep the names straight. Thank you Rudy for you quality control. Later gentlemen.
