I've looked and looked (mabey overlooked) but cannot find a torque specification to re-mount the front sub frame on my 81. The car originally came with a 267 V8, now a has a 355. I'm using new factory rubber bushings (it's my wife's daily driver). Also, what is the best way to measure the subframe for accurate alignment (from a point on the body, from the center of the rear hubs or from the yoke on the differential, or all the above?) I just want to ensure it's right. Thanks in advance.
