The 126 is essentially the 116 2.0 so there is a lot of compatibility of parts but not everything will swap. For the interior, the front seats will swap over but nothing else will. I'm not 100% sure but I believe that the floor pans are different enough that that switching over wouldn't work. Most of the drivetrain components (from the motor back to the rear diff and axles) will swap over without modification (driveshaft probably requires some modification). Front brakes are a direct swap upgrade but I think rear might be the same as the 116 but don't quote me on that (also the gen II brakes require a 15" or larger wheel). Brake booster will not swap between. I think the steering box is the same but not sure. Window regulators is a no. Radiator and oil cooler will swap over fine. The climate control system would probably swap over but would require a lot of modification. A/C system itself would also probably swap over, probably would need some custom hoses.
