Kombi front seats... again?!

Hi,

I know this has been posted before, but i searched and couldnt find what i was looking for. I've got a 77 bay kombi and am looking for replacement front seats... i heard somewhere that the easiest solution is to grab seats from an early 90's magna (or similar) and just use the rails that come with the seats, bolted straight through using high tensile bolts, rather than try to modify them to suit the exisiting kombi rails?? Only catch was something to do with the rails having to be the correct distance apart?

any help please? 🙂
