Reclining seats. Custom seat rail?

[Dazecoop]

Thinking about replacing the standard Peugeot seats in my car with some kind of reclining bucket seats. Recaro or similar, as I really like those.

However, seat rail is the issue. I found these

But at £95 each, I'm wondering if someone has done a custom rail for cheaper? The seats I am looking at are base-mount, and I must have them on a slider rail, they cannot be fixed to the floor, as that would be a pain.

Has anyone done anything like this? Either modifying the original runners to mount to different seats? Or by perhaps using something like this?

I've done some searching, it appears its a lot easier on a 5dr 306 due to the way the rails mount to the floor. Mine is a 3dr  

Thanks in advance!
