Thanks for the replies and helpful info. Just got back to the 'roo today and cut a longer 6mm x 1 bolt so that it was about 1/4" longer than original. After chasing the threads with tap all went well with new bolt and a lock washer... THANKS GARY! Thanks too for info about free FSM downloads. We actually ended up finding workable links here on USMB for 1989 models. BTW the torque values in the FSM were identical to Chilton's/AllData at 4.3-5.1 ft. lbs. Not really sure what the Haynes is all about at 80-97 inch pounds, but we ended up at 60 inch pounds for all 4 bolts. The Loctite thread repair is actually an epoxy and release agent for "creating" new threads that are supposed to support up to 128 foot pounds when cured...I would suspect it is about the equivalent of a combination of JB Weld and petroleum jelly! Here is the link at NAPA:
