I used flat fiberglass sheet (phenolic would be good) that was then bonded to the surrounding structure. A metal plate could also be used instead with AN3 bolts to secure it. Placing the threaded ends forward as previously suggested would allow one person torquing. A Sharpie line on the bolt end would confirm that it didn't rotate. -Bill Wade ----- Original Message ----- From: "billhogarty" To: Sent: Sunday, December 20, 2009 10:38 PM Subject: [LML] IV-P Engine Mount Bolts > Another FWIW: > > Tightening the engine mount bolts is a real chore because the sound > insulation, upholstery, seats. and floorboards have to be removed.
