      70 Chevelle bumper bolt sizes for install

      I have the brackets installed on the bumper and need help with the bolts to install it.

      I don’t have the bolts anymore. After searching it appears the bolts are 7/16 coarse thread 1.5” and 2.5”.

      4 bolts inside the truck

      2 bolts behind the fuel door to body

      2 bolts for bottom bracket to body

      Can anyone confirm the bolts and their lengths for each
