So today I finally took a seat out to show pics.
This model Recaro.

The seat rails are 400mm apart, same as a stock Galant seat.
I used the rear factory holes (after testing which ones where best suited), and re-drilled the front holes to suit the Recaro being fitted.
The Recaro's I have use 6 bolts instead of 4, so I had to drill 2 holes in each rail.
I also had to use the plastic spacers that came on the factory seat so the adjusting mechanism could still work. Without them the seat fouled on them and stopped them from working.

I also had to bend the adjuster arm down at the front as the Recaro's are longer and the adjuster arm tucked up under the front.

Bride Lowmax seats are able to be fitted using the same method (the same mod was down to 77galantv6's car for those seats).
