Engine part #'s vs application

[maroon81GS]

I've got 2 GS1000 engines that I'd like to try to ID what GS applications they are originally from. They have the following p/n's........1) GS1000-101304 and 2) GS1000-104511. Can anyone tell me what year / model these engines came from? ....or where can I find that info?.
Thanks

Bump
Common guys! No help here for a newbee? I've tried the search feature with no luck. Someone must be able to give me some answers or point me in the right direction. I would very much appreciate any help from anyone!!!!!!!

Hello maroon81GS, not sure if this will help but at z1enterprises.com they list bikes by serial #'s

Hey mate.
Pretty sure they are both '78 "c" models as the '79 "n" model engine numbers start at about 121000.
Hope that helps
Looks like Jim beat me to it

German info

Mr. maroon81GS,

This PDF file on the German site www.gs-classic.de contains a lot of information that may be useful, but you'll need to use a site like http://translation2.paralink.com/ to translate the column headings. "Rahmennummer" is frame number, "Fahrgestellnummer" is chassis number, von = from, bis = to, etc.

Thank you for your indulgence,

BassCliff
