I think that should be fine. I second the idea.89MustangGX said:So does your 'professional' opinion think a bolt that has a 1/2" of threads with thread sealer on it will be ok, or should I rethink my plan. I still have the tranny out (until tomorrow) so now would be the ideal time to change it if so.
I'm thinking it will be ok based on my past experience (with only needing a rubber cap and worm clamp), but it would be nice to have a little backup.
