Ok, dug them out
@eDaniel
They actually retained the original EP3 sliding rails and just cut off the mounting hole brackets below them and added the Preludes ones:
Front of drivers side:
Back underneath of passenger side:
So from the above pic of the passenger side I took pics of each bracket. It's the rear passenger side mount the needs the bolt left in place as the rail on that side is so long it goes over the bracket/bolt location. See here:
Hope that makes sense as I appreciate the pics aren't great.
Other rear bracket:
Front drivers side (still passenger seat):
I didn't take a clear pic of the front passenger side, you can see it slightly here, but it follows the same principle as the other front:
Hope that helps bud. I'd note that the seat fixed this way sits a little higher than OEM seats so if you're really tall you might be close to the roof. I'm 6' tall and with my old spiky hair it would occasionally brush against the headlining. I'm not sure if there is another way to remove the EP3 runner system and fit the full lude sliding rails a little higher.
But they felt great to sit in, comfy seats and a little more of a hug to keep you in place than the ludes tombstone design (I'm sorry but as much as I love them, soooo copied from Porsches).
Cheers,
