The Stovebolt Site Forums The Shop Area Driveline Pressure Plate mount bolts torque specs

I have looked through my chevy Truck shop manual and I am not finding the torque specs for the pressure plate on my 4 speed trans. I don't see any for the three speed either. So I am either blind or completely missing them. Anyone want to help me out>?

Thanks in advance

ps my search for the answer yielded over 1000 results that didn't have what I was looking for.

They're 3/8-16 Grade 5 bolts- - - - -30-35 ft/lbs. should be about right. Any standard hardware torque chart should get you in the ball park.
