[Healeys] Closest to BN4L 052381

[Peter Svilans]

Jim,

The early 100-Sixes were criticized for excessive scuttle shake.  This
strengthening hoop was introduced with the idea of minimizing this transverse
"paralellogram" movement of the cowl structure.

Looking into the engine bay of an early 100-Six preferably without the motor,
you see that the space between the footwells and upper bulkhead, (where the
bellhousing sits), you see a perfectly rectangular opening.

On all later Healeys, this space between the footwells is now a semicircular
shape hugging the bellhousing more closely.  This effectively "gusseted" the
corners of the rectangle, making the bulkhead more resistant to sideways,
transverse motion in relation to the frame.

Best
Peter
