Well I also got a 72 that I am going to start working on in a month or two , I can pull one of the bolts a measure it for you for the right size and length, then I can pull one from my 76 pinto parts car and see if they are the same too, good to know if someone needs this info in the future, it always happens when you take something apart , you ether have not enough nuts and bolt to finish it Or To many left over and don't know where they go 🙀
