I'm taking apart the sport recaro seats

OK people the zip sliders which came from amazon (5 different sizes) didn't fit the zip strip on the seat cover so I just sewed it together best I could and it works just fine.
The seam is never visible anyway, so I suggest you sew together yours too unless you want to swear for hours trying to get it to work like I did.
I also put a little bit of nail varnish where I finished so the thread would't come loose.
