Good afternoon at the time that Chris built my car he was using Alfa 156 door handles connected by a Tribute designed mechanism to link to the Z3 door lock (same as on Bob`s car *Hurnleft*) , although it worked reasonably on my car it did seize on 2 occasions and never really gave full confidence .
The latest choice is to use a Mini door handle with the standard Z3 handle fitted with a small plate attached as per (Andy`s car *Ericholm*) .
To convert my car to enable the Mini door handles to be fitted I have bought 2 replacement doors £25, 2 door handles £34.95 and 2 door locks £35 .
I have replaced a Z3 door previously and did not want to do it again , so I cut the required section out of the new doors (which the door handles fit to) and those sections will be bolted onto my existing doors .
If anybody need 2 Z3 doors with large oblong holes in them please get in touch! thanks Geoff .
