Fender Emblem Placement

[BigMike608]

I have some OEM fender emblems I bought off Ebay and I want to install on my 87, but the PO had the mounting holes filled when he painted the truck. I can't find any diagrams that shows correct mounting locations to place them. Can someone give me measurements for placement, Im thinking measurements from the body line and to the edge of the fender where it adjoins the door would be perfect.

All the original studs are broken on the back of the emblems and I would also like to know the best/most secure way to attach the plastic gaskets to the backside and then attach the emblems to the fenders. Thanks in advance for your help!
