Replace 76 a/c cab with 76 non-a/c cab?

[Shtudwn]

Hello,

I have a rusty 76 K20 that has a/c. I have found a 76 K20 non-a/c cab for $100.

Are there any concerns with changing cabs?

I notice that there is no cargo light in the donor cab but other than that nothing else jumps out at me. Both are auto trans. I know that I will have hoops to jump through in swapping VIN numbers. Anyone ever swapped cabs in Washington State?

Thank you.
