With some good cleaning and some work with a wire brush, I actually got it working!

I used some WD 40 extensively, and a thin razor blade to clean out the gap. I then used some paper speaker shims and compressed air to clean it out even more. I then used a wire brush to clean the rust off of the plate. Here are some before and after pictures:

I installed a diaphragm and hooked it up and got good sound out of it. I had another standalone 802-8G and hooked it up (both outside of the speaker box) and they sounded about the same. Definitely not a final test but getting closer to potentially saving this driver.

Question: do you think that I should still use the Evapo-rust?
