Default ID this Underdrive Pulley

Came with the car. Just curious which one it is. It's completely unmarked except for "MEET SFI 18.1 SPECIFICATION" terrible grammar and all. I thought it might be an ASP, but all the pictures look way different. Any help would be appreciated.

Looks like the one on March's site.
Like I said, it's an older one.

Use your imagination. It's round, it has grooves, it's not mine or yours...does it really matter.

Doesn't matter to me at all.... but the only thing I see in common is they are both pulleys and they are both black...

That is def. not a March. March has six fastener holes on the front for one thing... plus I see no where for the silicone which is the "fluid" in the damper....

http://www.machperformanceparts.com/mp/4505.html doesn't look the same to me..... The one pictured has no A/C provision though...

Whats the point. did you look at the link I posted above?
That pic I posted is of the pully you will see when you click on the link. Now click on the link, go to the bottom of the page, it says LS1 pulleyor whatever and has that pic of the same one this guy has. click the link ---> http://www.marchperf.com/pg1.html


EDIT: you can't get a more positive ID than this without holding the pulley and taking it to different companies and asking them in person.
