Robbie,
I did see a car at Mog18 in the as driven part of the concourse that supposedly raced & didn't have the trumpet.
I would come over & we could make say a papermache mould or 3D scan it but Bergen is a bit far.

The fibreglass on mine also needed repairing & I was wondering if a metal unit would be better pulling air in from above the rad.
