Nut & bolt size
Rebuilt my gold 350 and lost a box of bolts. I need size and grade of the bolts that bolts flywheel to the crankshaft , and the same for nuts & bolts for flywheel to torque converter on a turbo 350 thanks

TC to flexplate are 3/8-16 NC x very short, grade 5 or 8. Bolts sheet says:
0.5" long threaded shank
low profile 11/16 hex head x 0.23 t.
Use matched sets of 3 for balance
To minimize confusion, it's best not to refer to the ring gear holder on an auto trans car as a "flywheel". It has little mass and serves petty much no "flywheel" purpose- the Torque Converter mass does that.
As for the flexplate to crank, I have literally 100's of extras [thus they are very affordable], but no time to send any out for a while. Bolts sheet says they are
7/16-20 NF x 0.6" long, Gr. 8, 5/8" head
Special head with deep recessed radial lines
0.5" long threaded shank
low profile 11/16 hex head x 0.23 t.
