Man, I like the first '67 and the '70 console. I guess you're concerned about the implosion hazard during and even after cataract removal, totally understandable. I think there are ways to completely replace the bonding material.
The '70 has an Ultramatic tuner. I saw a video that shows one in action close-up, pretty awesome.
Here's the video, tuner action starts at about 2:15.
