Unfortunately still not rego-ed, but getting close.
A couple of fiddly things which may interest Cobra builders.
The fit of the one-piece front section precluded mounting the windscreen washer nozzles in the cowl area so I routed them up behind the wiper arm pivots. I ended up by using spray nozzles from garden watering systems. I had to experiment with a few, i.e. shape the deflector with a Stanley blade to get the right spray pattern, but it worked out okay.
After the few short test runs I was surprised just how much crud was thrown up by the front wheels and trapped in the rear of the front guards. I'd roughed out some splash guards earlier
(edit - from 1.0 mm sheet steel) but they became 'gunna' jobs, so I've now finished them off and fitted them.
