Don and fellow morganeers,
the note below on the BRTB, was on Don's second Super Sports at least, it
was a tube, flattened at each end and bent at about a 45, with an
appropriate sized hole to bolt to the top of the kingpin area, then came
medially and back onto the frame near the aluminum stop block. These
were used to stiffen the front suspension and prevent brake chatter in
some references. I have also seen a set on Jake Alderson's Baby Doll
spec. car in Sheffield England.
