I bought the kit for $40 - $45 dollars. Pretty easy mod. Need a grinder. The only thing I did differently was reuse the rubber boots that were on the original swivel joints. The new heim joints were a little larger so some trimming was needed.
Tourer - It sounds like you reused part of the original linkage and had to drill out the rivet. I ordered DHS-11252, and it already had the linkage modified, rivet removed and new heims installed. Mine was 100% complete and ready to install. I did have to send back my linkage so that DHS could modify it for the next customer.
