New here and really need help

I took apart basically the same van as you and there is nothing on the floor for mounting a seat. Its just bare metal.

Sounds like you are on the right track with the transit seats. I am trying to build out a transit currently and the seat bottom is 15-18" off the floor. You should really measure that before you start. They are super tall. The metal legs alone are like 12" high to the underside of the seat.

Thanks for that info. I will definitely do some measuring before committing to those transit seats
