Dave,
I feel I bought mine fromReddifast Steels in the Birmingham Area.
My problem wasn't buying it (once I found it) or cutting it (once I fitted a new blade in my nodding donkey mechanical hacksaw) but ..... bending them the radius required. People will tell you they've used the Steel Boiler on their 6" model to shape them round - didn't work for me. Additionally I shaped some 3" x 2" wood to the radius and clamped the spring steel inside for periods up to 7 full days - didn't bend at all. I'm off to a known leaf spring maker north of Manchester in the next 2 weeks to negotiate with the to heat the spring steel up, shape it and cool it in oil.
Lastly, when calculating the radius you're drawings may show the Leaf Springs at their 'standard' position ie in my case with c 1/3rd of a ton bearing down on each set ....
Best of luck and f you can answer any of the above please feel free to pm me with any suggestions.
Kind regards
Andrew
