old Yamaha Enduro/Dirt seat I.D.s needed

[DogBunny]

I acquired these two seats in a trade. I tried I.D.ing them myself, but there are zillions of different small vintage Yamaha bikes to pore through. Any help appreciated.
The first seat pan is very similar to the 72-73 AT2, CT2, AT3 and CT3, but that's not what it is.
Thanks in advance.

the second one looks like the one on my 1979 80cc, but that was 30+years ago. google images look same, but unsure. I tried ebay 1979 80 seat, but nothing.

Thanks for the help. The second one does look like a 79 YZ80 until you turn it over.
The only way to definitively I.D. seats is by their undersides, and the only way I know to do that is to look at eBay listings and then look at the underside pic if there is one, which is very time consuming with all of the different models.
