I looked on E-bay and found a emblem for over 100 US.   

Its called a hood emblem and it has a part number. 

I'll show the link just for reference

The 2 Emblems I have, I "believe" are rear side emblems

They have no part numbers on them.

They have the tabs to hold and are really nice...

I think 100.00 for 2 would be a deal.   

If interested PM me your address. 

After I get confirmation from Todd that Cdn Poncho has received the funds, I will mail out at my expense...
