Correct side emblems?

So although Ive sort of tried to fight it off I have pretty much everything to change my 68 K20 from GMC to 68 Chevy.

Im wondering what would be the correct side emblems. I looked at a bunch of pictures, but nothing definitive popped up. Looks like a lot of guys just take em off, which is a look I also like. But since i'll have it all apart I thought it might be kind of cool to put the correct emblems back on. It is running a 454 now, not sure if they have the engine size numbers that look stock with 454 one them.

I also have a 72 Burb 4x4 I may as well start looking for the correct emblems. It was a K20, but being put back together as a K10. It has the lower belt molding and the upper trim that goes around the base of the windows.

Neither truck has a correct spid, so it will be sort of a guess. If you have any pics of either that you know are exactly stock that would be awesome ... thanks!
