Just google for 8KC3-0726-0250 and you will find many shops that sell the 25cm version. The 25cm version is a very close fit but it will fit. I ship the v4.1 with the 30cm version because it is much easier for the mass production process and for user installation experience.I ask all of my resellers if they are interested to sell the 30cm riser only and there was no interest so there is no option to buy it.
