[oletrucks] 51 A/D 12 volt question

[N8rux@aol.com]

Hey everyone,
I have a 1951 1/2 ton that is being converted to 12 volt.  Does anyone know
off the top of their head what size battery I will need....Preferably Sears
Die-Hard (gift cert from the wife).  I know I could just measure it..thought
this might be easier.

Thanks
