well I did some more research and talked to illnastyimpreza who is running this tranny and he used the old speedo gear out of his 98' impreza tranny. He has had no problems after 20K miles. I looked up the part number on that on and it's 32714AA190 and was a wopping $60, where the 32714AA230 was $12 and from a 04' forrester with the 4.11 ratio.
I want to buy the 98' impreza one to compare, but that is a steep price tag. I wonder if there is a difference, or if any speedo gear from a 4.11 tranny will work. I used the one I did from reading a a post from a vendor on here that had done the swap.
