Check this website www.autoexpress.safeshopper.com/. The alternator on my 1988 750 went belly up wednesday. I went to autoexpress website, found my alternator, and ordered it. 140 Amp, rebuilt Bosch, three year warranty and are you ready $165.00 which includes a $45.00 core charge. Bottom line, after shipping cost I was out $174.00 with $45.00 coming back to me with return of the core. Can anyone beat this?
