Early A bodies had a unique bellhousing for the htree speed and the four speed, they will not swap. Later A's had a common three and four speed bellhousing, will swap. If it's the later A then the clutch linkage swaps too.

They say there is always the exception that proves the rule.
Don't be the exception.
