So, anyone who’s seen a real GT40 will know the sills look like this.

ie with some lovely beading in and I wanted to replicate that.

The original ribs should be 1.060″ (26.924mm) wide by 0.240″ (6.096mm) high according to http://www.racingicons.com/gt/process.htm

While not quite right (but IMO close enough for a space frame replica!) I noticed you could get a 1″ (25.4mm) wide by 3/16″ (4.7625mm) high half round aluminium strip for a very reasonable price.

A bit of cutting later and I had 4 long and 2 short strips. Then hammer flat the ends

and grind them so they are round.

These will go here

I’ll stick them on the sill tops with some Sikaflex 252 but they’ll look something like this
