Hi Julie,
you have the same car as me and I am thrilled with my choice. I also saw that New Zealand partial conversion but in my opinion this is a much better way to go, so good. I have done a complete right up, posted under a different heading on this forum. I have re-written and corrected it more accurately and more completely and have it as a word document, Which I can send you if you like.
As long as you are reasonably handy you will be able to follow all my instructions, combined with pictures from Simon who sells the units from Estonia
Cheers John
