yeah its pretty sad.
they didnt build too many V models and i havent seen a VO yet. theres a guy in the tractor photo gallery who couldnt find V sheet metal so he just used the tin off a VA. looks odd but whatever works i guess.
if you ever get your project off the ground let me know. id love to see pics of it. and if you cant, id trade my restored VAC for a rusty old VO any day!
you could always try the tractor wreckers, some of them are hooked up to a cross country directory so they can always track some tin down for you. the other option is "the dealer" but that may either prove expensive or fruitless.
