Chassis Question

[67see10]

Are the 63-66 c10 frames the same for 67-72 c10? I see that a lot of parts (mainly suspension parts) range from 63-72.

I found a 64 Cab, front end, and Stepside Bed that is in pretty good condition that I can purchase for almost next to nothing. The only thing is, it comes with a 80s frame that the parts are just sitting on (nothing bolted on).

It's easier to find a 67-72 frame where I live than a 63-66 frame.
