I would call the local wrecking yards....won't be new, might not be blue, but you might get lucky.

The thread on Great Stuff insulating foam got me thinking about what you could do with stuff on a car.....and I thought of my footrest. It isn't broke, but it flexes when you shift posistions, which feels odd to me. I was thinking of SLOWLY, adding the foam behind footrest to solidify it's posistion. This stuff has great adhesion qualities and gets semi-rock solid....it might work in your case.
