*All '72-up (calendar year) AMC sixes and V8's have the same bellhousing bolt pattern. Only difference is depth of the bellhousing and consequently the length of the transmission input shaft. They can be interchanged. | *All '72-up (calendar year) AMC sixes and V8's have the same bellhousing bolt pattern.

*There has been a report of a T-10-to-early inline 6 bellhousing (aka “Mexican” bellhousing). It's definitely the right shape for a GM bolt pattern, although it’s not drilled. But there are no GM trannies with an 8" input shaft that seem to work with it. | *There has been a report of a T-10-to-early inline 6 bellhousing (aka “Mexican” bellhousing).

*While the transmissions may be from different manufacturers, the shifter is always AMC. Columns in most AMC/Rambler vehicles are AC-Delco manufactured and therefore can be swapped from a GM product of the same years, but the shifter marker is in the column itself in most AMCs, while GM used the marker usually inside the dashboard near the speedometer. | *While the transmissions may be from different manufacturers, the shifter is always AMC.
