Need help with a Bull Pup Trigger Linkage

My uncle is a machinist and it is unfortunate for me that he sold his home and with it his work shop. Getting older forced him to down size so all of his shop goodies were sold as well. A year and a half ago I bought a custom stock for my Blizzard. I also bought a custom trigger linkage for that stock from the maker of the stock which never functioned properly. Had I known my uncle was looking to down size I would have dealt with this sooner. I am looking to see if anyone can make me a linkage that would function with this stock? I don’t have the machinery necessary to do the job.

Thanks
