Must get the delivery driver to avoid and speed bumps just in case they break.

4130 is just cro-mo (stuff thay make bike frames from) so i dont see why you are tied to using 4130 rods (there is prob not a exact match in wire or rod anyway) you do have to take care not to over heat and harden it more like meny other metals.
you should have a look at some of the classic racers thay used hardend tubing and brazed everything together
so the tube wasnt over heated and hardend more.
i cant see why a roadster needs anything other than a mild steel tube realy and a seemless one is a better option if you can get it.
i got some for my roll bar back stays from a hyd hose co. and was fairly priced
