Hey guys , recently acquired a Yost and I believe it is a 204. Has 4-in jaws. It has a fixed base but was hoping to make it a swivel base. I found the swivel mount on eBay but need the center bolt and lockdown hardware. Was wondering if anyone on here might have these parts or if they knew where to get them. It was made in Muskegon Michigan so as far as I know it was made anywhere from 1950 to 1980 but not positive about that.
