Reverse Spam - Blower Pulley Cover Wanted

[mondorally]

Looking for an upper pulley cover for BBC with 6/71. The pulley itself if approx. 5" or 6" in diameter with the wide belt. I'll post up pics later.
Anyone have anything that may work?

Anyone? Here is a pic of the 6/71's in the 27'. Different motor but same pulley setup as the one I'm looking for.
