Yea, your right Jonny, it is a different profile.
I made contact with a number of rubber companies yesterday and Friday evening. In the process, I became aware that the shape I was looking for is an 'A' frame - with a flat base. The base is the bumpers contact point and the cut/gap/space in the top center is 1 - 2 cm. In a nutshell, the profile is simple, but not that easily sourced.
Surprise, surprise, the original strip can be sourced from a few elite retailers.......... @ 10 times the cost of this one!
The height of this strip is 3cm shorter than the original but it's purpose and design is otherwise the same. If it's not [for some reson] fit for purpose, when I receive it, well - it cost less than a euro, so I'll update on the outcome.
