Lower Front Shock Bolts

I was wondering if anyone knows the size and length of the bolts for a 1967 Barracuda Front Lower Shock bolts. I am putting new front shocks on the wife's car and noticed someone has put what looks to be all-thread in both lower shocks mounts. Thanks!
Here is one from a 63 Valiant. They are probably all around the same length. Any hardware store should have
a grade 5 or grade 8 bolt that will work.
