well I had this car 3 years ago, it was '70 850 SC, light blue mtl. I had 903 ccm *it's probably yours 896* 40 kw.
I was wonderful car, I made a lot of work on it, I got new front axle, new gearbox and Alu wheels....*they were actally from Uno :-)* this car had sport exhaust by Sebring I guess, nice sound and some more HPs.
the only one problem was with starter, after longer drive was so hot it was unable to turn with engine, I made new bearings but this failure was probably made by Fiat, my previous car Fiat 600D had starter from side of gearbox and was cooled by air, but here was right next to engine block and very hot. I guess the reason was oposite sense of rotation of this engine.
