Signal indicators

I put them on my 68 fastback ,center of the fender , right in line with my hood pins , which are in factory holes in the cradle , dont remember what the holes were for , its been so long,, look factory good ...put them where you like them , its ur car ...
My memory aint all that today but... didn't the 68 fish have it's turn indictors on the hood and not the fenders?
I never understood the need for the things anyway. They were just repetition of indictors in the inst' panel.
Fender mounted turn indicators on fenders on VW Beetle served a purpose.
