G'day from Down Under. I find myself the owner of a 1968 convertible that, on the evidence (it's still in USA, so I'm going on pics) is a 3 speed manual (which makes it "rare" with only 326 built*, but not necessarily desirable) and originally carried the base 327/300 motor, but now has a 69 or later shift console with a 327/350 i.d. plate and 4 speed pattern.
(The evidence: trans: there's no reverse lockout on the shifter; engine: the tach is redlined at 5300 rpm**, i.d. plate: 68s didn't have engine data plates***)
My query: I haven't seen a 68 three speed console plate in any of the catalogues or reference sources I have. Was it / is it available?
