The best type have a tapped bolt hole on each corner.
I used to have a CRX that had this so you might be lucky.
I've got impresa sti seat's & they just need a bar each side & bolt the bars to the seat box(just like honda's). Easy
 
Vectra gsi recaros going in mine. They are totally flat bottomed on the fixings. Little deeper but am fitting a strip further back on the box giving more room.

That and cos my mate breaks them i got the pair for £60 and in near mint condition.
