why are these different? i see the bolt hole bracket are located in different spots longitudally. any idea which mounts belongs to which tranny/motor? are they different between 1750 or 2000 gtv?MichealS, Here are photos of the 2 styles of mounts, plus some other parts from the same storage box.
Maybe not the whole story.The transmission mount that is sloped is for a 1969 dual circuit brake mc USA Series 1 1750 GTV Spider or Berlina.
Was the sloped trans mount used in later models after the pedals moved to the firewall?Maybe not the whole story.
The 1969 Canadian Spec GTV AR*1362163*, single circuit original braking system, had the more rearward placed chassis mount for the rear trans mount thus requiring, as you call it, a "sloping trans mount". This allowed clearance for the longer under floor dual circuit MC.
This of course made it quite easy to install the 1969 USA Spec dual master when this AR*1362163*, ex Gunter Mayer/ex Bulova series racer was restored in the 1990's.
This all came to light at Roman Auto Prep when the more common trans mount would not fit and the original for the GTV was in Toronto. There happened to be a 1969 USA chassis in the shop so that trans mount was borrowed for the racer.
It is possible that assembly line economies drove all "69" chassis' to have this rearward mount, but I do not know.
