Wider view side mirror needed

Hi all mk 1 experts,
I am looking for a pair of side mirror to replace my existing one to adopt to the heavy traffic in Hong Kong, do you have any suggestion?
The original one just too narrow and difficult for me to observe the next lane when driving.

Thanks
Leo

Porsche 944 mirrors would give a wider view and they should go on with little hassle  

if its an early car they may be flat glass, later ones have convex glass which may help a bit. you could fit caddy mirrors
