I have a question for you guys, I just noticed the latest 68 mo block for sale on ebay, the one in the 68 orphan section , well i noticed the casting date of b 26 8 and the engine stamp V0304MO almost exact matching numbers as my 68z28 and they look normal, but the VIN #s is where there is a big difference that vin# is 18n423426 and mine is 18n399959, my question is how there could be such a large gap in the vin#s thanks for any input
