Is there any room to tap a thread in the block behind the plate? I just don't remember. Another idea is you could drill out the plate, and weld a threaded insert into the larger hole. Perhaps enlarge the hole in the alternator bracket to fit around the insert. That would give you a longer thread for the bolt to go into. Not sure how much torque a .160 long thread would hold.
Thinking back, it was one of the other front plate holes that I helicoiled. Maybe the sealing block?

Naturally, most of those repair methods involve special tools for insertion.Not sure if there is enough room for these or not. Sounds like a heli-coil is out of the question based on the plate thickness. Is there room to use a jam nut (skinny nut) on the back of the plate? http://www.mcmaster.com/#standard-rivet-nuts/=kmgbbf Alex Thomson _______________________________________________ [email protected] Donate: http://www.team.net/donate.html Suggested annual donation $11.47 Archive: http://www.team.net/archive Forums: http://www.team.net/forums Unsubscribe/Manage: http://autox.team.net/mailman/options/spitfires/[email protected]
