Hi Simon,
I had the same problem as I was going to fit the old side
repeaters from my Golf on the Polo, but as you have discovered
the bulb holder is totally different!
The Polo connection is better and more secure IMO,
but anyway that's good old VW for you!
My advice would be to see if you can get hold of the bulb
holders and wiring, try Bob Lawson from the MkIV forum
he is a VW parts guy, he should be ble to help you find the
part you need. His number is 07719552509, tell him Steve
from the MkIVs forum refered you.
Hope this helps
