Not sure about the gear ratios but they are essentially the same thing.

there are some diffrences between them .
156 and 159 2.4 ones are diffrent in the height of the axle, I believe it sits lower on the 156.
All the mounts are alike.

3.2 petrol has a diffent bell , starter is mounted on the front.

All 2,4 gear ratios are the same, 3.2 are diffrent off course.

I would be interested in getting a longer 6th or end ratio if you can find them

the 156 didn't use the F40 gearbox in combination with the 1.9 engine. totally different.

it's possible, but can't see a reason you'd want to, and it'll be a lot of work to create fitting driveshafts.
