Can someone give directions on replacing the barrel pin on a Gen 1 SRS. Just got one used and noticed it is damaged. Works fine but somebody definitely wasn't gentle in putting it in. Flattened on the front.
Called DTA on Friday to get new pin and info but nobody home. Try again Monday.

The online manual says see page so and so to replace pin but there's nothing there.

Thanks.
