Hi Armando, first I will like to say sorry for my bad English...
Thank you for the photos. The upper rails (with Recaro Black knob) are originals. The lower rails on seat are not original (look at the part for high-adjustment!). The rails beside the seat are not from bucket seats. They are upper rails for sport seats. I have them if you need them. You can't use them on bucket seats. The letherette and the cord(?) is not original. the lehterette must be fixed with Nieten (dont know the English word) on resine. There must be holes for it, can't see on photo exactly. Be carefull, the resine seats are often replicas... Easy to make, but not original. The originals have metal inside. Can't say from photos if they are original or replicas. The Recaro logo on photos is to high. Seats are for co-pilot/passenger.
Your parcel is on its way. Hope that it all comes to you save. Can not guarantee (resine seat). Give me mail when it all arrives.
