I've got a 6AL basically over the top of the Renix rat's nest, i.e. right about where the diagnostic plug/ relay brackets go. Mine's rewired though and there is no longer anything in the way there. I just used some scrap aluminum and made a shelf with a couple bends, riveted it down.
By the way, a 6A fits perfectly just below the back of the hood, I had one bolted down right on top of the smog info sticker. However a 6AL is bigger and won't go there.
