Those are questions that I cannot answer without seeing it in person. I will say this. I like the timing chain tensioners so much that I modified one to fit on my 331 Hemi. They work well, however, I have seen where people had trouble with timing set types other than Cloyes. Something about other make chains don't line up just right and tend to "saw" away at the tensioner shoes. Cloyes makes those for Mopar Performance, so the Cloyes chain sets seem to be a good match. Make sure you get the Cloyes tensioner, instead of the MP unit. While they are the same piece, you will pay a higher markup for the one in the MP box.
