Tom, I just bought a new stainless steel bolt. The female threads in the thrust pin were stripped so I tapped them out. I don't have a slide hammer, but vice grips orthogonal to the bolt, using the harmonic balancer to pry against got it out, but it sure is one tight machine fit. I'm sitting here looking at the destroyed tension rail and destroyed chain tensioner. The tension rail is the original steel rail with rubber backing. Half of the face the chain tensioner rides against broke off. The contact surfaces of the tension rail and chain tensioner were both chewed up something horrible. Miraculously, the camshaft timing is dead on where it's supposed to be. Ordering new parts, so should have it up and going in the not too distant future. I'm replacing the other chain guides just as a matter of course. Can't see the bottom one's without removing the little plate, but the top chain guide is pretty worn. Thank you and everyone else for their help.
Ralph
