Dashmount kit for Fabia, any ideas

I got a handsfree mounting unit at a steal at 11 pounds something from an
accesory website, which is actually model MBC-6 and far cheaper than many
other websites.
I noticed that in order to prevent damage there is a dashmount kit
available, but its even more expensive than the unit itself. A shameful
explotation as far as I can see as all it is is a bent bracket of metal with
some holes in it which pushes into the of the dashboard.

I may plan to fabricate my own perhaps using anything I can find at DIY
stores if I dont have any scap brackets at home. Anyone know any alternative
bracket sources or ideas before I do this? Self adhesive is out of the
question, trust me my father works for a famous adhesive brand and these
arent intended for long term.

Thanks
Tony
