Thanks for the advice. I have tried a few times to get the 8mm in the top bolt with no luck getting it to seat in the hex top. I tried cleaning it out but still no luck. I haven't really had the time to play with it a lot but will give it all a try this weekend.
It is in a sort of bad location, but I had an old buick that the first step was 'remove the engine' to get the starter out so I am pretty happy.
that thing took a lot of hammer blows over the years.
