I have both the 157 and 164 tooth bells, and I have a 157 flywheel and spacer plate.
There is a 5 bolts (1964 1/2) version of the 289 and the 6 bolt (1965 and up model).
The stock bell is a 157 for all 1965 1966 1967, from C code to Shelby. The 164 was on Galaxie, etc. but you can use a larger flywheel.
I am in Texas, and the bell and fly can travel in the same box. I accept PAypal.
