Vorshlag has this brand new 14 pound PC680 AGM battery ($168) still in the box + a Odyssey HK-PC680 hold down kit ($138) for the same battery. Both are brand new, never used.
These are a great way to "drop weight" from your street or race car, and total retail on the battery + bracket is $305 - get it all for a steal at $200!
NOTE: Does not come with the brass "SAE" terminals shown in the scale picture, but these can be purchased for about $10 online. This adapts the M6 threaded posts on the battery to a round vertical post that most cars use.
