180OUT, can you send me a photo of what your seats look like in the car?
This is what the seat looks like. This one is sold by GT Car Seats in Austin and is identical except for the recliner mechnism. The BF Torino mechanism is a Reuter "wheel" adjustment. The basic design, however, is identical. I had my seats upholstered in gray cloth that is similar to the oem material. These seats are replicas of early 911S seats made in period by Recaro. I'll post a photo of my seats in my Super. Unless the vendor has made a change, the supplied "Guilia Berlina" seat rails don't fit. I easily made my own mounts using 2" x 3" tubing. If you upholster these seats in a style similar to what Alfa oem seats look like I think they look satisfactorily period correct. The raised side bolsters also do a good job of locating you during hard cornering.
They're not particularly hard to pick up and move around. Lighter than, for instance, Recaros. Despite being light, they're also quite well made. My upholsterer commented on how nice they were to work on. The BF Torino site lists their "Le Mans" style seat at 13.5kg.
