Topic: Need help identifying this seat

[bandit1]

I bought a new seat on ebay listed as fitting a '72-'73 CB500 only it doesn't match up to my seat off a '72 CB500.  It doesn't match up to the tank or any of the hardware off my seat.  I emailed the seller to see if they would reimburse me, but would like to know what model this does go to in case I have to eat it.   Sure wish I could've seen the pan before buying, that would have saved the aggravation.  Here's some pics.
And here is the listing http://www.ebay.com/itm/230741176204?_trksid=p3984.m1497.l2649&item=230741176204&viewitem=&sspagename=STRK:MEWNX:IT&vxp=mtr

After digging thru the parts fiche, it looks like the description in the ad was correct and I have an earlier style seat and hardware on my '72.  Looks like the slide catch I have was on the '71 and the plunger catch was on later models.
