When Sideclips came in for maintenance i only repaired them on special request, and only if i still had the necessary parts of course.
Problem for a while was that i only had one 5-wing torx bit left, and Leatherman did not send us new ones.
So when that torxbit broke we had to stop repairing everthing that used those screws.
AFAIK parts for Sideclips are no longer made, and as i had only a very limited amount of spare items i took old ones apart that were beyond repair and used those parts on other Sideclips.
Made a few oldtimers very happy that way, as they also did not want to part with their trusted Sideclips.
KF4's were not repaired due to the riveted construction, but replaced with other KF4's as the company still has a few in stock.
When these are left, the customer is given a call with the question what he or she would like to have in the same price class.
