1968 Montego MX floor shifter???
 

I'm going to look at a 1968 Mercury Montego MX Convertible this week and it says it has the C4 automatic transmission and the 302 V8. It also has a splint bench seat or what I would call bucket seats. The shifter is on the floor. My last Montego had a bench seat with the shifter on the column. My question is... was this an available option for the Montego in 1968? Or has this been modified to a different transmission?
Thanks for you help
