Rubber kits can be wrong, so you are best to workout what you want and order those
Also are there different quality in rubbers as one of my machines I need to re rubber was recently fully shopped out and the rubbers look almost new but keep breaking which has never happened to me before. I figure they are either really cheap or really old stock.
A couple of years ago I did hear of a batch of rubbers from a supplier (cannot remember who) that broke easily
I guess rubbermakes can make a bad batch sometimes
