I have a Taylor battery relocation kit. It is the brushed aluminum box like GMHTP used on their silver drag car.
I can't remember exact numbers but I know that the kit was over $100. The box itself was around, $85-90.
All the cables and clamps etc are in good condition.
Only thing about it's 'condition' is it has a black 'Hoosier' sticker on the lid, but it should peel off if you want.
$50
