LYCOMING ALT DRIVE BELT 37A19773-382
A friend, no really, had an alternator belt break and we had a tough time finding one. Turns out another pilot had one stashed in his plane. Correct fit. I ordered one to have as a spare in my plane.

These are quality belts from Lycoming and I will get years of life from them, what more could you want
The Engine belt was great, in stock and shipped from California to Washington. The shipping however was $16.50 for a single belt which took over a week to get here, and in my thoughts very high priced for shipping. It was just normal shipping also, not express our overnight.
