My original generator is not charging the battery and I plan on adding ac next year. I have been searching the internet for an alternator and mounting bracket that would bolt in on the yblock. I have a big problem - most alternators with mounting brackets use the bolt hole location where the oil dip stick housing is attached to the block as the pivot point for the alternator. This bolt hole location has a sheared bolt stuck in it and will not free up. There is no part of the sheared bolt that is exposed (sticks out of the bolt hole), infact it is somewhat recessed. To drill it out probably would require the motor being pulled - there is not much room/clearance to manuever to get at it and be very costly to do so.

Is there an alternator bracket for the 292 yblock that would bolt in and not use this bolt hole location to anchor the alternator? I saw one that I thought would work, however another site (concours parts) listed the same or very similar bracket for use without ac and as I stated above, I plan to add ac. The site listed a bracket to use with ac and uses the bolt hole location with the sheared bolt in it!
