I'd like some Captains Chairs in my Trainsit but...

(sorry in advance, the text editor does not let me put paragraph breaks in!) I didn't realize it would be so difficult to find some captains chairs for my 148" Transit, but am finding it a challenge - even in Houston, TX. I keep coming across www.shop4seats.com/‎ when web searching but my phone call to them today was mediocre at best. The sales lady, seemingly quite knowledgeable at first, didn't seem to understand that Transits are a competing product of the Sprinter. They have a whole dedicated line of seats that work with Sprinters which have integrated seatbelts, but for non-Sprinters (i.e. "Econo-lines") we would be limited on selections because non-Sprinters do not have the ability to reinforce the seat (plates on the bottom). Even though I said that we are looking for seats for the Transit, at the end of our conversation she asked "what is the make/model and year of your van?". We want to put 4 of the best (comfort, durability, safety, and just plain awesome) captains chairs in the rear of our Transit followed by a bench/sofa/bed seat in the back. Does anyone out there know of any places (preferably in Houston/Texas but could go further out)? Thanks!
