would a towbar from a 2005 (mk1) octavia fit a 2007 mk2 octavia ????

No, I very much doubt it, the cars are on different platforms.

ok thanks

ok thanks

You could look at a tow bar manufacturers website eg Witter and see if they have the same part no listed for both vehicles.And then just check with them to see if tow bar will fit both mountings. Sometimes alterations to platforms are cosmetic.
