68 Cuda grill studs............ Any tips ?

I loaded the Cuda on the trailer to take to the bodyshop today, mother nature decided not to let me , it started raining, So I pulled the trailer back into the barn.
I took the other half of the grill off the header panel today , it only took about 30 min to do. Next I will drill the rivets and replace all the studs with new.
Where can I fine the small rivets at ?
This grill is not for a show car , it doesn't need to be correct , just look good.
Also , what paint can I use for the grill surrounds I have a ding I need to straighten on one side also .
