Didn't 118 have double strands of 25 chain like this?

Also, I would suggest some serious stress testing (the way my team did this for our octocanum systems is setting up one of our 6 wheel drives and spending a couple hours having the 2 drives pound each other, it was the only way we could recreate the failure for our mk1 system)
