Chevy & GMC Vans

Would someone mind measuring the driver's side seat height from the van floor to the top edge of the seat's bottom cushion? The distance from the floor to the front portion and the distance from the floor to the back portion of the seat cushion. I am doing a custom installation of seats in my van and I tossed the original ones and misplaced the measurements I took. Currently the seats are too low and I'm trying to adjust them to the proper height.
Thank you.
