I've been working on a 914GT project and have created a couple replica slider sets for that, based on original Scheel sliders. In the process I've also created an extra replica set for sale here. An original set was used as an example and all parts are fresh zinc plated. These are the later style and have all 3 later style slotted holes in the legs present and can be used on scheel bucket seats, but have also been seen on recaro rally seats.

On the last two pictures you can see how to identify replica's from originals, original levers tend to be a bit more elegant (left hand side) and the reuse of the lever holder that is on top of the sliders will show with some extra welds on the holes that occur because that part is drilled off and then put upside down to create the GT setup.
I would like to get $800 for this very nice set and I'll pay for the shipping of them. (it's a set for 2 seats)
These are SOLD
