Nico,
To the best of my knowledge as told by the dealership at the time, and I think I still have some paperwork on it, the factory mounted the battery in the trunk on all '63 & '64 car equipped with the aluminum lightweight package. All steel cars had the battery mounted in the engine compartment. All steel cars for '63 & '64 could have the trunk mount battery package, but at extra cost.

Subject: Max Wedge Question
Was watching the Mecum Auction, today (a rerun) but they has a supposedly true (1 of 28 remaining) Max Wedge 63 Plymouth savoy post. I am not an authority by no means on theses cars but the one at auction (didn't go any higher than 50K) had the battery in the normal driver's side inner fenderwell. I thought all Max Wedges had the battery in the trunk or was this only done on the 64 cars? Any info would be appreciated. Thanks
