Rubber bush on throttle pedal

Having read through a string of helpful posts from 2015 on the subject of refitting the hook on the pedal end of the throttle cable and its rubber bush, I've now been forced to give up (again and purely temporarily) as I fail to see how the new hard rubber bush is replaced in its ring on the pedal assembly.  The main problem seems to be that the bush is very hard  and very snug plus I can't get both hands anywhere near it!  Please can someone tell me the secret of doing this, step by step and without suggesting I need to lose weight!

It should be soft squishy foam type rubber

As I under stand it a good wine bottle cork whittled down a bit works as well.  There were 2 styles of Bushes one was large and the other smaller so make sure that you have the right one.  I can't remember if it was year based or transmission based.  

When mine went south, it was a foamy type of rubber, and I went to a laboratory supply house and got a rubber stopper with a hole in it and whittled it down,  I also used a fender washer on the other side so the rod went through on the left and the washer on the right as well as the clip.

The Mk2 Golf used a hard rubber bush which last longer than the soft foam type fitted to a mk1 Golf.

To fit the hard rubber bush make sure it's warm as it softened the rubber (place it in some boiled/hot water for about 5 mins) and use some grease on the bush to help it slid in.
