WSM Page 39-48, 24-29 ft-lbs. Replace the lockwasher.
Sorry, someday I'll lose my right foot, or my right arm, and I'll update the spreadsheet to include all those automatic transmission torque values. Maybe.

That must be for an earlier year Rob. Mine are M 8 panhead bolts, no lock washers. Stating ring gear is part of the flywheel on my 86.5. I torqued them to 33 Ft lbs . Should be good.

33 ft lbs. for the six front flex plate to flywheel bolts. No lock washers from memory and a check of the PET diagrams.
One must be careful to not exceed this ft lb. torque setting since you will strip the threads in the aluminum flywheel.
BTDT.
Cheers,

These bolts are grade 12.9. 33 ft lbs is the correct number.

Thanks Guys. 33 it is. Constantine clamp all torqued, lower bell housing back on and crank pulley bolt finally torqued. Woohoo! Now just have to get the headers on.

Thanks Greg!
For some reason I thought a portion of the flywheel was aluminum.
At least it sure acted like it when I stripped the bolt hole.
Good luck with the rest of your project Art.
