[Healeys] drivetrain vibrations

[HealeyRick]

Keith,

I've seen the article about your transmission box reinforcement:
http://www.britishcarweek.org/scuttle.html but it doesn't mention the chassis
rail reinforcement. I'm trying to picture what you did.  Did you take two
pieces of 1.5 angle on each side, basically capping the rails?

Thanks,
Rick

Martin et al,

As part of my BN7 resto I wanted to take some structural measures to eliminate
the shakes.  Among other things I welded in 1.5 angle iron on the tops of both
main rails from the motor mounts back to the crucifix.  Welds were about 2
inches spaced about 2 inches apart.

I also welded in the 3/4 angle iron inside the tranny box as I call it and
added more weld on the cockpit side of the tranny opening.  Balancing the
drums was also done.

No hard data but the car has no shake or rattle - just roll!
