I did this this morning using a Drill with Gatorblades. The pictures below show both backrest posts. I cut the Utopia to the same (oops almost 1/4 short) length as the Ultimate post. The Ultimate has a groove on the backside that is for a spring lock. I measured the mark and used the same Gator blade to cut the groove in the Utopia post. I beveled the edges on the Utopia post on my grinder. As I said I cut it a wee short but it goes in and a little pull up locks into place.. I am showing the pictures before I painted the Utopia so you can see the work. Now I have a choice of which to use. I prefer the Utopia it is bigger and as you can see I have it almost touching the seat where the Ultimate lacks any up and down adjustment and was not as comfortable. It also gives my wife some edges to grab on accel ( I never knew she did this before the Ultimate and I felt her fingers).
