Beggs built as FFs:

FM3: 3
JM1: 1

Beggs adapted into FFs:

The '05' Keith McF car was essentially a FF except the category hadn't yet come here when it was racing. It had a 1500cc Cortina motor.

'02', the Rootes powered car, became a FF and indeed still is. It has spent way more time with a Kent in the back than it ever did with a Humber 80.

Not sure if 06 ever did time as a FF - possibly.
