Hello, I Am currently looking for some Cobra specialty tools and wanted to know where to find them. The main tool that I am looking for are the lower unit spline socket for removing the pinion gear/nut(part no.311875). The others are all the shimming tools (part nos. 314438, 984329, 328367,). I am also looking for advice of weather it might be cheaper to have a shop do this or do it myself. I am very capable of the task I just don't no wich might be more economical. Is a shop going to have these type of tools or is some monkey just going to wing it and not tell me. Any advice?
