hood pins? length and diameter?

OK Guys,

Ive Been down this road before and still didnt get a straight answer.
Will these work on a 73 Duster , remember the hoods changed in 73 and the mounting hole are different, Bryce calls me today and tells me he has bought these off E-bay and wants to put them on soon. Has any body used these or similar on a 73 on up Duster if so can you post pics of where you mounted these

Thanks, Bob/ Bryce
