I went and really goofed up - Aztek Question

Well, I picked up a 470 on Ebay, pretty cheap awhile back. I have used it a couple of times, and like it well enough. Anyway, I took it apart. Not because there was a problem, but because I take stuff apart to see how they work. I can get it back together well enough, but now I discovered I have lost a part to the assembly. It's the little red do hickie that goes into the foremost assembly. It has a small steel pin sticking out from it.

SOOOO, is there anyone that knows of a place that I can order this part, or if someone out there that may have a defunct Aztek that they would like to sell and/or part out, I would be so greatful.

I am a bonehead, I should not have taken it apart. I think it's some sort of mental illness or compulsion or something.

Thanks in advance,

Ted
