Hey again. Hope you all had a great 4th. What I found was that while my truck was being stored(while I was on deployment) someone was tinkering with it for me. They claimed to put in a new throwout bearing(centerforce) which was still in the box(found it) and the engine plate is not installed. I looked at the starter to find it binding(frozen) against the flywheel gear. The edge of the tooth on the starter is touching the tooth on the flywheel. Bum deal! I do know the block is a 66. Could there be a different starter for that year compared to the 76 I thought it was? Also is there a such thing as different tooth patters-meaning a finer area for how they are cut. Like having two 168? tooth flywheels,but one is cut different? Thanks for any help.
