I was just wondering if accord seats would be a straight swap into a mk5 prelude advise please

No. But Which accord do you mean? None will fit directly.

Any really from 99 to recent so it be modified rails etc

I can understand wanting to fit type r recaros but standard accord seats dont offer anything else over prelude seats, Maybe bigger but I find then too big compared to the Preludes.

The type r would mean a rail Change etc
