http://www.z-tekmfg.com/datsuncat.html Just in case no one hase came acroos this before here it is.. I would get them but My water pump is electric so it would kind of be a waste.. They got other cool small stuff to..

yum yum yum! I wish I had access to a CNC machine!

Nice...no other company makes them?

MSA has some stuff like that... or just go to a machine shop & say... "hey! carve me a Z in a spare piece of aluminum"

Not that I have seen

I had gotten some billet accessory pullies off Ebay a couple months back, but I've never seen them again anywhere.
