I have the 69.5 RR A12 hood pins,
trim & lock pins with lanyards on my 68
got them from Year One 10+ years ago
can't remember how much, sorry
I liked the fact the lanyards were attached to the lock pins

Dzus fasteners are another choice too
depends on how much room, where & how thick
depends on the hood or body panels how thick etc.
need to know how thick to order the proper depth & sizes
many come with the backing plate & springs,
some come with rivets even
some minor fab work
bending some steel or alum
90* plates to mount under the area you wish to hold down
possible some welding of tabs or some riveting will be necessary
They're available at most all performance, fabrication or avionics
parts supply, Jegs Summit etc. has a decent selection too
That's what most people use on racecars,
they're light, easy to install & do the job well
