Ok, i may have found an oversight on my part: the blind holes are pretty shallow and the bolts are pretty short thread wise. When ChryCo used rtv on the original bolts, some ended up on the nose of about a third of those through bolts when they were removed. If i installed one of those unnaturally long rubber tipped bolts in a shallow blind hole, i may have only caught a thread or2 before bottoming out, pulling those threads right out at 50 in/lb torque. Ill have to look tonight pulling each one at a time with a bucket handy to clean any dick-nose off the bolts and hopefully find a few threads left in that hole.
