Cab Questions: Non-A/C v. A/C

[austinstocker]

I have an A/C cab that is in amazing condition, and want to swap it on to my NON A/C truck. Since I do not have the heater box ect. off of my truck right now, my main question is: How similar are the cut-outs in the two cabs? Can I simply patch off some holes from the A/C cab and bolt up a Non A/C box to it?

Any info would be appreciated.

As far as the vents in the A/C cab, I will probably patch them or utilize them rather than cut the complete dash board out.

Thanks.
