here I am with the next "dumb" question ...
our car came with 2 point seatbelts (no Porsche logo on it)... so we really do not know being originals or not. The are fixed "between" the seat mounts with shown material.
We would love to have seatbelts in the car as driving in Europe is different to the USA. Preferably 3 point belts.
Any idea's how to install belts (without restoring the car - it is still a driver

any lead is highly appreciated

cheers from Holland ...
