Will the front seats of an DA Integra (year unknown) fit in a EJ6? I know they'll be some work, but will it be worth too much trouble?

 

You shouldn't have any real difficulties putting them in. If there is an issue it will be with the rear mounts on the seat rails. I just put prelude seats into my civic hatch and thats what I had trouble with.
You can either drill new holes in the rails or take the rails off your old seats and attach them to the new ones. If new holes in the seat rails won't allow free movement on the sliders, then plug the old rear mounts, and drill new ones.
When you drill new ones, it's best to go with a nut and bolt with a washer on the undercarriage. After you have them bolted through the new holes, spray on some anti-rust paint so you don't have to worry about corrosion. Good luck

 

thanks for the info man
