I bought this last September from Tractor Supply for about $90.  I put it in my '49 Jeep thinking that it would easily start the 4 cyl.  It definitely did that plus burn out my stop and new turn signal bulbs.  I remembered we put 8 volt in our 6 volt tractors and they worked perfectly including the bulbs.  I had to go back to a 6 volt for the Jeep.  We put about 200 miles on the Jeep last fall and parked it inside our heated garage over the winter.  Switched out the battery last winter and have been trying to decide what to do with it.  It's basically still a new battery.  It's located at Staab Repair on 13th St. in Hays.  Dimensions are 9"W x 7"D x 8"H.
