mounting grill badge
Slybones and I agree on placement.
I went down to the local h/w store. Picked-up some 5/16 SS hex head machine bolts, nuts, lock washers, and fender washers. Also picked up some rubber washers, same size as fender washers, and some JB Weld. Pop the hood, open halfway. A third hand might be good to be sure you have the badge on straight. Mark the back of the badge thru the honeycomb pattern, 2 places

(funny, it looks like a hex head bolt). Rough up the area on the badge and level/rough up the top of the hex head. JB Weld bolts to badge, wait 24 hrs before mounting. I put the rubber washers between the grill/badge and the grill/washers, for protection. OOPS, HUMA, get some Loctite

backup for the lock washers
It will look cool when you are done and it ain't coming off.
