In my Brother's scrap yard I found two 165's with the added Hydraulic remote control valve body. So far I have not had any luck getting either off. I want to put one on my 165. I believe there are two bolts holding it on. The bolts are recessed in the body. I think they should be allen head bolts, or cap screws. Problem is I don't see an allen head down in the hole. There is something similar but I don't find any flat sides and the hole in the center is way too shallow. As I mentioned there are two of these, each has two holes and all of them look the same? What am I missing? I have tried allen wrenches and torx. I have scratched around in the hole to see if I can knock some rust out but nothing helps.
