Any pics of that anywhere around here bax? Don't remember if I've seen your setup before.
All three of the previous panels fit easily (semi-easily?) into the stock space in the glovebox.
The Centech is designed around their smallish 10-fuse panel that fits with very little trimming. But if mounting it to a metallic box/surface, you do have to create an isolator gasket of some kind (I've used gasket material and leather and cardboard before) to keep any of the circuits or main connections away from conducting material.
The Painless is not only designed for it, but actually includes a pre-cut plastic glovebox already made for their particular fuse box.
AAW probably would fit as well, since it's very similarly sized to the Painless box. It's got a slightly different flange area, so not sure if it's a breeze or might take some head-scratching, but it's probably doable.
Might also depend on the design of the lid/cover too. Sometimes the AAW box lid is hard to remove, so that should be looked at.
The Painless and AAW boxes are actual boxes, with weather-resistant lids (VERY weather-resistant in fact) and the Centech is a true "panel" and not enclosed at all. Still, it's one of the nicer looking setups, with an open-faced but nicely finished decorative surround letting just the fuse heads show through. Looks very "hot-roddy" in your glovebox. Even if it's not as sophisticated or protected as the other two are.
