chuckw mounts would work with a tubular member. Im sure the stock mounts would also work except for both mounts im pretty sure you need the lower half. The piece that has the stud and big nut on the bottom. Youd have to re use the lower and the mount its self. And even if u got chuckw mounts youd probably still need the lower half. Unlessss the new member has a different design or lower mount already built in.
