Need Recaro seat rails for '67 912 Targa

[bmwloco]

G'day from the South Pole (yeah, really!)

I'm only hours away from leaving "the ice" after a 14 month stint. My 912 is patiently waiting for me in the "Air Cooled Garage".

I picked up a pair of refurbed Recaro Seats from http://www.2002parts.com/html/recaro_front_seats.html - my housemate says the're absolutely stunning. The price is right too - two for the price of one.

My question: does anyone know where I can get proper seat rails for the Recaro/912 mate? I haven't had much luck looking thusfar.

Thanks!
