The prototype Montreals had a common Alfa 105 trans that proved inadequate for the V8`s torque. Subsequently they used a ZF for durability.
The one in my "Coupe" is sourced from a Maserati and the gear ratios are similar but closer ratio to the Alfa 105 but the 5th gear is a .86 or .88 (can`t remember for sure but too low with a 4.10 R&P).
The shifter assembly is quite long on both the Monty version and Maserati trans, but I shortened the one in the "coupe" as the V8 was moved rearward about 4 inches from it`s position in the Montreal for weight balance. The Trans originally came with a U-joint output flange that is the same as the Alfa u-joint design which lends conversion to a 1 piece driveshaft conversion easily.
There are many ZF boxes in German built cars which can be used in Alfa conversions. There are pics of my modified ZF in my build thread: Spider improvement Effort.
