I love the look of wires on the Roadster.
When I originally built my roadster back in 1986 I fitted adaptors and wires like you.
WARNING: Make sure the wire wheel seats correctly onto the tapered part of the adapter. I had loads of problems with mine until I realised the wheels were seating onto the top of the wheel studs. After grinding them back flush with the wheel nuts I managed to get them to work correctly. Hope this makes sense.
