The aluminum framed side windows with the smaller sized 'vent' windows are something Holman Moody did (in addition to Gas Rondas second car, ive seen them on the first iteration of the Batcar). The R Model frames are unique to the Tasca car, something they did during 1965. At least one race in 1965, they also had an R Model rear window in it. Bondy Long bought it for 1966, at that point, the standard rear glass was reinstalled but the R Model side windows remained. Carson Hyman drove it in 1966 as Bowani Ford, and Sam Auxier match raced it in 1968 as Bowani II, also drove it in NASCAR Ultra Stock. The R Model side windows were still in it when it turned up a few years ago
