I think all you got to do is to add cone & cutout volume to rearchamber, and remove reardriver volume from frontchamber. (cutout volume depends on from which side driver is mounted. Remember polarity might be reversed (or not if phase shifts at crossover freq)

Atc should be an area not a volume?

Yes, I just showed how 1108 was calculated :)

ATC and vtc should be switched around

From where you use 1.8 in the calculations. The plywood here is 12mm thick.
Please let me know what do you mean by ATC and vtc should be switched.
