Does anyone know what type (length and thread pitch) of bolts and nuts are required to secure a 5.0 Alternator/smog pump bracket to a 302 block?
I am piecing together a serpentine setup from scratch for a 74 Bronco and am off to the hardware store for my stang and I am hoping to get everything in one shot.
Thanks much!
