Torque specs for gear box.
Just need to know what the torque spec is for the 3 bolts that bolt on the gear box to the frame. Thanks.

Re: Torque specs for gear box.
I have been working on these cars for awhile and I am not sure what three bolts you are talking about. Maybe a picture would help.

Re: Torque specs for gear box.
Their torque should be the same as for any other hardware.
Torque goes with hardware size.
That size hardware should be somewhere in the 80 ft-lb range; not quite as tight as lug nuts, but close.
