1971 C-20 Longhorn SM420 to 700R4 conversion

I am swapping out the SM420 in my 1971 Cheyenne Longhorn C-20 with a 700R4 and need to know if and what type of flexplate or flywheel I need to get to make this conversion work or can I use existing flexplate? Please advise.

Manual transmissions use a Flywheel, Autos use a Flexplate.

153 tooth flexplate & '92-'96 Corvette/Denso replacement starter...... Flexplate bolts, Torque converter bolts, & starter bolts are available from you local GM dealer

What about an nv4500 5speed to keep it manual?
