Need help on finding props

A customer brough me a model to upgrade to R/C.  The model was built for static display but now I'm trying to convert it to R/C for the customer.  Here is the problem, the original modeler installed 5/32" diameter shafts in the model with the appro. sized bushing tubes.  The static props are a soft white metal type.  I need to find 1" minimum (better if it is 1 1/4")diameter props but they need to fit onto the 5/32nd. shaft. Hard metal brass or steel. Does anyone know of a place / source in US, Canada or ever over seas?  I can't seem to find them.

 Thanks
