[Fot] To be seen at the Kastner Cup

[John Styduhar]

There must have been modification of the BETA chassis to accomodate the
TR4s wider floor pans and engine bay.  I've saw a very early TR4 frame that
had extension plates bolted to the top of the outriggers to fit the wider
body mounts.  The diagonal braces for the front spring perches also had to
be moved outward to fit the TR4 front inner fender mounts.  I don't think
the BETA had wider floor pans that the stock TR3.
