Hi Richard1974!
I have managed to find one pair of headrest. Must say it was not easy.
One scrapyard trow away all R4
Second one have whole seats and does not want to sell only headrest.
On third one i managed to collect two decent one from 4 cars!
Will post you pictures and then you can decide do you want them or not.
Front side
Rear side
Right one on pictures is smoother when you touch it
Left one has more rougher texture
And some damage on side
I have washed them as they were covered with dirt and spiderweb and threated them with sonax black for rubber and plastic
They weight 2,691 kg
Paid for them 150kn, and shipping to Uk up till 5 kg is 110kn.
That would be 260kn total and with todays exchange rate 1GBP=8,195KN it brig us 31,726GBP
If you want them then we can arrange payment with paypal and i can send them to your address sometimes next week.
