F100 Frame Question

[kpowers4]

Anyone know if a 1973 F100 body (cab & bed) would fit onto a 1966 F100 frame without modification? Anyone know what year(s) the F100 would fit on a 1966 F100 frame? Thank you in advance!!

Don't have a real definite answer,....but 1966 ends an era. 67 to 72 is another. 73 to 79 was the beginning of the bigger F-100 series. I would say some modifications would need to be made to the frame to accept the larger cab and bed. My 2 cents.
