Thomas Crown Replica

[TC Replica]

Help - I am building a TC replica buggy and need some chrome capping to go around the top of the screen as per the original (see picture) - only problem is that I have used 5mm thick screen material (3 mm to flimsey) - so I need some chromed U channel with an inside dim of 5mm. Does anyone know of a supplier in the US -or anywhere? no luck in the UK. an alternative is chromed right angle - size 5mm by about 10 mm, Can anyone help Martin corvairdunebuggy.com
