First build...rookie questions?

[spacegrass]

I wanted to throw this out there for those of you who have more knowledge than I in the matter....

Im looking to take two of my trucks and combine them into one..
The trucks at hand are a 72 C-10 6 ft step side, and a 67 C-10 8ft step side. Both are in tough shape, but workable.
I have 2 questions...

Will the 72 nose bolt up to the 67 cab without issue?
And will the 67 cab sit on the 72 frame without issue?

Just getting the ideas rolling and your input would be greatly appreciated...

Thanks.
