1964 Impala SS Convert 409 425HP help

[Brucebodyman]

any thoughts on what a 64 Impala SS convert numbers matching 409 425 HP dual quad 4 speed fresh frame of restoration might bring in todays market. red red interior white top. i cant seem to find any that have sold recently that were real deal numbers matching cars. anybody have any idea how many dual quad 425 HP converts were built in 64 it also has the dealer installed removable hard top with complete owner history from new. any opinions would be appreciated.
