Hey thats a coincidence that is the same as the two I bent earlier this year on my Dufour. I went mad trying to find replacements but finally got them for £65 each delivered from Kenneth Ryland at www.sanshin.co.uk. They are Goiot 822s or 823s. You'll have to wait about 5/6 weeks for them but I don't think you will find them cheaper anywhere else.
Also the fun starts when you try to take the old ones off. Good luck.
I gave up on the aluminium ones and got my tame stainless steel man to replicate them. Was about 5 years ago but they worked out at £20.00 each. Gets away from the s/s and aluminium galling problems as well. You would need gasket material or equivalent between s/s base and alloy toe rail. So far working a treat!
