Does anyone know offhand what the torque spec should be for the flexplate to crankshaft on an '87 4.0?

Thanks, that's what the old mitchell guide stated for a flywheel, but didn't mention flexplate torque. I recall it being around 55 lb for a flexplate, but that seems a bit low.

Double checked in my Chilton and Haynes. Both say 105 lb for the flywheel and the flexplate. The converter takes 40lb.

Thanks for the double check. I torqued it to 105 w/ loctite, now I'm good to go.
