I'm looking for the correct 12V battery that was trunk mounted in the SS Cars. I'm pretty sure I won't find a "live" one, so looking for any that have a Very Good condition case. I'll probably try to install a new battery within the old case, for the proper appearance. The pic is from Mr. Potter's '63 Plymouth, and is the look I'm going for. I believe the original batteries may have been a bit longer. Thanks for any assistance with this.
