Sparco Seats Installation question

[neuralracing]

Anyone have pictures of their installed Sparco Seats? I am having trouble getting my sliders (which are already attached to the side mount brackets (needed those because Sparco Revs are not mounted from the bottom)) to mate up with the base mounts I bought.

The bases have like an arm sticking up... I wonder what thats for (seatbelts???).

 

[Flash]

I've installed Sparco seats before.
The arm sticking up should be for the seat belt buckle. As far as mounting... the sliders mount to the seat. The tab brackets is what they are called, mount to the sliders. And then bolt that tab brackets to the base. Then mount the base to the car.
I'm a bit confused because my friend has the Sparco Rev's and he has the side mounts, and they aren't adjustable.
Can you post some pictures please?
I hope what I said helped you a little bit.
