Kei reclinables bride rails type

[Skifledanabit]

Ok, got some kei racing seats, managed to manufacture the passenger side in ok, I\'m having a lot of trouble with the drivers side, as its totally different mounting holes wise, so I\'ve decided to bite the bullet and get a bride seat rail for the drivers side, one question though... what one do I need?

Btw, what I did have left the seat really high, leaving me to keep cracking my head on the roof, so I\'m going to need a low rider whatsit for the rails.

Although if anyone does have a cheaper alternative, I\'m all ears.

Thanks in advance
