Just started putting a lock right in my d35c. Everything started good but then the couplers that slide into where the side gear was are too big. They dont fit in and are noticibly bigger. The side gear washer wont fit over it either!! What is the deal here. The box says it is for a d35, but I cant imagine why it wouldn't fit. Any help would be great, or i will have to call them in the morning.
