Used leather seats from a Renault Megane RS. You need a OMP HC 782 mounting plate and a pair of Recaro runners.
It's not a direct fit. The OMP HC 782 is specific to the Fiat Coupe however, it did require a slight increase (45 degrees inboard and backwards) to front mount holes to match floor hole locations. Additionally you need to drill the OMP HC 782 mounting plate to add two holes at the front, and extend holes at the rear to match the Recaro runners. Please look at the pictures of the mounting plate in the link above.
You need to space (I used washers) the mounting plate and runners to allow space for bolting to the floor at the front. The rear steps down and is inboard so that's fine as is. Measure twice and drill once. I also needed to space the front, between the car floor and mount plate, to allow for a vertical gap for the bolt that holds plate to runners. I needed to place a couple of spacers at the rear to allow for the carpet as the OMP mount plate is flat and without it will bend the plate and push runners out of alignment. There is a side view photo in the above link that should help.
I did the passenger seat first which took me an afternoon to figure it out. The drivers seats was done in half the time.
In summary, 1) you need to add two holes at the front to mount to plate to the runners, 2) extend two holes at the back outboard to mount plate to runners. 3) Extend the front two front hole at 45 degrees inboard and backwards to match the Coupe floor locations.
