Are you asking about the bisquits that support the body on the frame?

[jtchevy350]

yes the four that bolt subframe to the car

The factory assembly manual for my old '67 F-Body lists 75-95 ft/lb. That's a pretty big range, but the subframes are similar on the Nova. That probably doesn't help a lot, but it might give you a clue. They're evidently nothing ridiculous like 200 Ft/Lb, and nothing really light like 30 ft/lb to allow movement. If the mounts are similar, the sleeve through the center of the bisquit controls the crush depth and resulting movement of the joint, so bolt torque is more of a fastneing security issue than controlling the flex of the mount. Given that the weld nuts in the floor pan are basically full depth, and the fasteners are nothing exotic, it appears that the torque specification is based on the common torque for any 1/2-13 Grade 5 or grade 8 bolt.
