Re: ZF \'box for sale
Yes the Pantera ZF is upside down compared to GT40, ring gear and pinion have to be flipped ( unless you want 5 close ratio reverse gears ) and holes have to be drilled between diff and gear sections for oil to drain through.Special tools are necessary to remove output shaft bearings unless you have a month to spare. There is a lot of ZF info on the Pantera Forum and manual available from Pantera shop.
