I don't have an old bulb so, here is my solution for the steering wheel wire,
First I heat the plastic bar and stretched to the wire thickness. Picked a wire for twist base...
... rolling up
I pass over the flame of a candle
Side by side with the steering wheels
Almost in the finishing line... this is the last detail I add, those connectors are showed on the picture sent by gasdriverca, thank you again.
Rounded bar for hose or wire and hexagonal bar for connectors
Painted
The wheels were assembled
I hope to finish or close by that in the next weekend.
