70' Small window cab ?

[Mater/10]

Hey ya'll!

I Know i know " There's no such thing as a 70' small window" well im talking about a 1970 chevy c50 cab with small back window. Im wondering if i can use it to build a 1 ton pick up and it look like a 67 1ton pickup. Will the front clip bolt on ? i know the bottom front of the cab is a bit different but i have been wanting to build my family a toy hauler. Also i wasnt to sure if this belonged in the big rig section or the pick up section since i want to use a big rig cab to build a pickup. Anyway Thank you All for the Great info you have i can wait to hear it!
