Anyone know what the torque specs are for the rear control arms mounting bolts on a 1969 Chevelle ? I can't seem to find this info anywhere. Someone told me 70 ft. lbs. Is that correct ?

70-90 LBS FT With axle held square to centerline of chassis & springs in position.

It is also found on page 62 in the AIM:yes:

Thanks for the reply. I am replacing the bushings with polyurethane bushings, will this change the torque specs on the mounting bolts ?
