I have a 1971 903 sport spider engine. The engine is in a 1961 Fiat 600. The rotation is still counter clockwise. Has the 850 transaxle, all is ok. Can any other 850/903 distributor be used that would be shorter in height? Asking ,to be able to shut the engine hood. Currently a Marrelli distributor. I've seen 850 Sport Sedans with shorter distributors. Thank You.
