I doubt you could do these yourself for the money, unless you could design them and had a cnc machine capable of making the inserts and did not count your time. I just got mine back from being upgraded, Clark is great to do business with and IMO his stuff is top notch. The Stud and adjusters he makes to use with these rockers are beautiful, sure they cost $$ but for a limited specialty product worth it....they are also legal as purchased from Clark.....
my 2 cents...

It sounds like the difference between the west coast rule book and the east coast rule book. Is it legal to do this or not ? Travis????????
