That won't happen, I asked him a question about his one time and he politely told me he sells them so he wouldn't be answering my question which is good business since he is selling the product. A simple look at his though gave me all I needed to know to measure for it though.
Simply measure you actions front to back and then in diameter and add enough room for the four bolts and feet with roon to spare because you may have to work on a larger action. You should be able to figure it out without too much trouble. I made mine to work with the LA and SA and it isn't too hard to measure for that either. I picked up some bolts with snap on soft feet from McMaster Carr so once I threaded them into the steel, I simply snapped on the feet.
