Cornwall clone

Howdy. I've decided to build a set of Klipsch Cornwall clones as my next project. I've built two kits from CSS Audio but they come pre-cut and are pretty much foolproof. I can easily find the rough drawings of the Cornwall 1's. So I know this build is going to take a lot longer than a kit but I'm having a hell of a time finding plans for the model 3s. I've seen pictures of builds that clearly don't have the Gen 1 drivers installed so I'm assuming those builders bought the larger horns and reverse-engineered the plans. The speakers in the 1s are mounted inside while the later ones are surface/flush mounted. Can anyone point me in the direction of cabinet plans for the more recent types? I'm pretty sure it just comes down to speaker placement on the front baffle as the horns changed over the years. Thanks in advance.
