cranks shaft #3830099

i'm trying to see if a forged crank from a later model would fit in my 1967 block with a forged
crank. so i can use the transmission from my later model with the lock up in it
because the 67 crank has a small hole at the end of crank and the later model tranny has bigger
shaft on it . so they don't line up.i read that the 3830099 crank might have the same size hole at the back that i could swap it ????
