Tim, been gone for several days so just getting caught up.

Take the link above to their site, then click the "Where to buy" internal link........they list 30+ dealers in Florida. Also, it wouldn't surprise me if they made the ones for NAPA that rocknrod referenced, so a check with your local NAPA store might be in order. As for your mounting question, I wouldn't want to guarantee anything on that. I always mount them in the "normal" position. I don't see any reference on their site as to this question. Since it's a drycell, it would seem that you would have some options, but there may be other factors than just leakage to consider. Considering that they're almost equal in dimension in all directions I'm not sure there'd much much benefit there. I would suggest you write them directly for an answer, or contact one of the local dealers to see if they know. It's been a while since I bought my last one, but if I recall it was somewhere around $139.00.
