I'm liking the set up but I have one question do you think it would all fit with the battery in the stock location or does the battery need to be moved to the trunk
From initial measurements, in factory form, yes, the tray and battery would likely need relocated. It is not the battery that is so much the offender, is the tray. If set on leaving the battery up front, maybe shorten the tray. I notice the tray appears over-sized with today's physically smaller batteries.
IMO if someone was looking to reduce weight on the nose, moving the battery to the trunk would be #1 on the list. The aluminum bracketed compact P/S pump and Sundin compressor would be #2 and #3.
