Use the search for a pattern...you have to drill holes for the seats and belts.
Cut threads into the top piece of the tub for the sea backs. Use stainless nuts and bolts with a squarec plate underneath the tub for the feet of the seats, some nice rubber handmade "washers" will help to keep vibration ad noise down for your passengers and when you are driving alone....
