I think we discussed that way back when. If I remember correctly you had to modify the control valve push rod to get the correct lift settings. If you have checked and resealed everything there are only two things that will cause your problem, cylinder safety valve and linkage.

I have been off PM for about 4 years. It got so I was having to check about six places every day and running the board was taking up a lot of my day because people were asking questions direct rather than using the board. Whilst I do not mind, I must put my work first so it is easier to have just one place to contact me and that is via my e-mail which gets checked every couple of hours normally.

The earlier lift will fit the Super Dexta as will all the parts except the quadrant.
