hello

our company wants to replace the bench seats in the 2010 express van with bucket seats. is there an existing seat that swaps out?

 

No. Quad captain chairs were only offered in the 2002 LT that was a short lived one off.
Good luck finding those seats.
I bought a set of swivel buckets out of a 79 van, and bolted them in. Its a huge job though. Rivets to drill out and splash shieds to move just to get at the bolts to the rails that the bench seats fit into.....
You could try a coachbuilder.....or conversion outfit.

 

I removed the passenger bench seats and mounting rails in my 2010 Express. Extremely difficult job! The best thing to do would be to have a welding shop make up adapters to mount captain chairs to the existing mounting rails. This could be as simple as 1/4" plate spanning the mounting rails having a bolt pattern to match the new chairs.

 

Careful when you make your own stuff. You may void your insurance in an accident...
