This is from the Tips section on that website. Note the final line of the quote. It appears from what they themselves say, pinning is not sufficient. So this kit with the pin would seem to be obsolete.



"A very common mistake is to lock the position of the balance bar by tightening the locknuts directly on the clevises effectively locking their floating action. THIS IS INCORRECT AND DANGEROUS. If the balance bar is to be locked after adjustment, all that is necessary is a single locknut tightened against a sliding sleeve to lock the thread against one pivot pin, thus allowing the clevises to swivel freely and maintain alignment with the master cylinder push rods and pistons. The sleeve must have a wall thickness thin enough to allow clearance in the clevis. Also, to maintain sufficient braking pressure on one cylinder should the other fail completely you must minimise the clearance between the two clevises and the steel tube in the brake pedal so that the balance bar rocking movement is limited to the angle necessary for the desired front to back balance, and no more.

NOTE: IVA compliance requires that, after the brake bias has been set to an appropriate and acceptable ratio, the adjustment be rendered immovable. We understand that drilling and pinning is no longer acceptable and that the locking nut must now be welded to the threaded shaft."

I beleive the IVA test has now been relaxed slightly so you no longer need to weld the adjuster it just needs to be locked so a pin would do fine.
pretty sure I saw this on here or on lcb a while back.
