I need an EGR valve!!!

[sd88supra]

I failed emissions because of too much nitrous oxide readings, so I removed my EGR valve and sure enough it was plugged, so I'm looking for one for my '87 n/a. Here's the thing: I found an aftermarket one from Autozone, which when I got looked nothing like the original, nor had I any idea of how it would replace the stock one. It was completely different. I don't know if that's because mine is a California car (I think the EGR system is different for California Supras), but the guys at Autozone had no idea what I was talking about.

I don't have 200 odd dollars to spend on a brand new EGR valve from Toyota (think broke college student), so I was wondering if anyone in the San Diego area could sell me a spare one lying around. I had no luck finding well-functioning one at a recycyling yard. Or, rent me yours! Thats right, I'll pay you to let me use it just to pass emissions. My temporary permit expires at the end of this month so I'll try to get an extension.

All of my numbers are good, just too much NOX readings. This is a simple fix.
