I've got two of these things...Does anyone know what kit you need to rebuild/refresh one? I know they're quite a bit different than a standard TQ, just not sure if you need a special kit for them or not. Most of the information I read online seems to be hearsay, as the two I have contradict what is being said (Size/Design).

One I have is in pieces, and the other is complete. I believe they're both 4846's, but the boosters are different in them, one has the "dual" booster, while the other has just a regular style booster for what it's worth...
