For original 911 RSR seats. as I know, there is the left seat rail shown in the above photo (#1). However, I don't have these seat-rails anymore. You can use the seat-rails (see #2 in photo) which were also provided by Recaro and I do have them. A
set of 4-pieces, I can offer them to you for 50.00 Euro but only if you buy the seat also. If you want origiinals, I can get one set (only) from a friend. The 4 pieces will cost 350.00 Euro.
