Would 67 Frame Rails work for a 64?
 

A lot of what i have read says the frames from 1st & 2nd gen C10s were basically the same.

Is that the case and if so would frame rails for a 67-72 work if i wanted to put together a frame from aftermarket parts for my 1964?

*Core support brackets are in a different location,

*Rear cab mounts are in a different location.

*Front frame horns are shaped for the era bumper so a 67 will be shaped differently vs a 60-66 bumper.
