My mechanic ordered an input shaft from a place called Sierra(spelling) a week and a half ago. It still hasn't showed up and there are only two more days till the 4th. Anyone heard of this place or have a contact? It's a wholesaler so I can't call them or I allready would have. The mechanic is swamped and is going to try and look into it today. It's looking pretty grim. I'm leaving for the water Wed. and it looks like I won't have a boat. This will absolutly ruin my summer. I'm very frustrated. Can anyone help?

Input shaft for a 1981 Mercruiser I outdrive.
