thanks for that, i am after a 126 to play with engine conversion, not sure what engine i want but i have a chance of a gearbox from a bis which i can play about with, your answer at least lets me know that driveshafts etc are the same so whatever engine i hook off the back will at least be able to connect to the car, i am fortunate enough to work for a fabrication company with laser and waterjet machines, and cnc machining and fancy a project, i like the look of the fire engines that people hook up, but i drive a 1993 micra every day and that 16v motor is brilliant, compact, light and might possibly be able to strap to a fiat box, thanks for your help, Mark
