help on AC to heater swap

Hello
I am swapping a non-AC cab for a AC cab.
I know the firewall holes are different.Can I just weld the AC holes up and re-cut the heater only holes and reuse my original heater only box on the inside??
Has anyone swapped out the AC for a heater when doing a cab swap??
It's a 77 cab and I'm swapping in a 81-87 cab
Thanks

I have done it on other vehicles and it is as simple as what you state.

You will have a few unused louvers on the dash where A/C only vents are currently too.

Okay then, time to bust out the mig....as soon as it warms up,I mean.

As for the vents, I'm just gonna swap over everything from the heater only cab. I'm in the process right now of stripping it down so I can have it sandblasted.
Thanks

Anyone else have any tips they ran across when doing this swap??
