Are you looking for the old body style or do you just need 8 speed erogolevers?
If you need 8 speed levers, you can buy a current set of 9 speed and convert them to 8 speed by buying Campagnolo part # EC-RE060
9 speed levers are the easiest to convert. You only have to buy and swap out the index gear. If you convert a 10 to an 8, it requires complete dissasembly of the lever because you have to replace the front ratchet ring as well
