Simply question, where do I get one? We're re-arranging our battery box, bigger and additional battery and I want to install a new/larger door so I'm after a complete door (solid or requiring an infill doesn't matter) with frame and lock etc, and yes I'll need to introduce some ventilation. Door needs to be around 370 X 700 apperture to be specific. I've been in touch with O'Learys but it's been 10 days and I have no answer on available sizes, I was told they have more than on the web site and some already on the web site, possibly likely candidates, have no sizes (or prices).
