I've asked this several times... Please explain how a bunch of folks who won't build the 08 and earlier car would be willing to build the identical car if it was an 09. #pretendimfrommissouri

240 Zs came with three different heads, two different carbs, at least 3 different intake manifolds, and two different transmissions across the production run from 1970-1973. How many spec lines should they have had when they initially classed the old Datsuns?
