304 flex plate

I have seen a lot of questions about 304 and flex plates for automatics. The tf999 and tf904 can interchange.

The Flex plates need for late model 74 and up the differance is the O.D.and Crankshaft Diameter:
Manufacturer : Pioneer Automotive Industries
Manufacturer Part Number : FRA-123
NAPA Flexplate 600-5055 Crankshaft Diameter : 2-5/8"
Flex Plate O.D. : 13 7/8"
# Flex Plate Teeth : 164

The Flex plates need for late model 73 and back the differance is the O.D.and Crankshaft Diameter:
Manufacturer : Pioneer Automotive Industries
Manufacturer Part Number : FRA-122
NAPA Flexplate 600-5055 will fit 304
Crankshaft Diameter : 2-3/8"
Flex Plate O.D. : 13 13/16"

The Flex plates need for TH400 differance is the Th400:
Manufacturer : Pioneer Automotive Industries
Manufacturer Part Number : FRA-108
NAPA Flexplate 600-5007
Crankshaft Diameter: 2-5/8"
Flex Plate O.D. : 13.83"
