Stock seat replacement - how to (re)insert rubber parts/knobs?

[Red Boll]

I picked up an Touratech set from a (former) Crosstourer owner today.
This is to replace the stock Honda set.

I removed the rubber parts/knobs from the original seat and want to insert them on the new seat but no luck. 
Is there some kind of trick to do this?

Applying some "teflon" spray dit not help. I do not want to use (sharp) tool so I just applied some pressure.

Acid free Vaseline and a bit determination.
Wiggling helps a bit but it won't go easy.

I will give that a try!

I've done it that way myself.
The previous owner lowered the seat by removing the rubbers 
Don't know how he was happy with that because the seat is moving all the time without the rubbers.

It took me about 30-40 minutes to insert the rubber stops.

Appearently acid free (white) vaseline can be found in a more advanced medical aid kit so I used that.
When one part of "the umbrella" is "under the edge of the "hole" it's a matter of "push&twist" for the round single hole stops.
The second umbrella of the rectangle stops are  a bit more difficult because you can only move that one side to side when pushing.

But it all worked out and the seat is fiited on the CT.

One issue (?) though. According to the Touratech instructions there should be 3 round stops at the sode of the tank, I do not have those on my stock seat.

I hope that the weather get's a bit better soon to go for a little ride.

Thanks for the tips!
