After I soldered in my new bypass diodes, I discovered a problem when I tried to snap on the cover of the junction box. Since the original bypass diodes were surface mount, this allowed the manufacturer to use a low profile junction box. The new, round bypass diodes were too high to allow the lid to snap shut like it is supposed to. What I ended up doing was I went to the Home Depot and picked up a 6x6x4 plastic electrical junction box. I then measured the thickness of the solar panel and cut off the back of the plastic junction box so that it was a little thinner than the thickness of the solar panel. What I ended up with was the new junction box without a bottom. It fit right over top of the original junction box and then I silicon caulked it to the back of the solar panel as shown in the photo below:
If you need to do this, make sure you let the silicone caulk cure for 24 hours.
