We scratch make our seats for the old narrow cars as most, but not all, modern seats just don't look and/or fit right. Attention to the seat riser and keeping the back low will make or break the out come. Pics show buckets in a 40 pickup and a bench in a 34 cabriolet. I like the bench but it's your truck so it's your choice.
