Steve - I saw what Brian did and for once I refrained from speaking my opinion. After tearing up a pair of motor mounts this past summer, not something I'll fool with. Granted, his is a low horsepower stock Rambler 6 and mine is a mildly modified 5.0, the effect is the same - and it can get interesting - like a close to full throttle shut off. Yours with a hood hinge or other low/no stree application - I wouldn't have a problem as a Gr 2 bolt could normally work.
