Here you go:

I have a 12MY NV2500 hightop. I just put in swivels on the front seats. I used the NortherTool ones that were around $80.00 each. I welded them to some angle iron frames and attached them between the seat base and the seat. I do have to crack the front doors about 2" to get the clearance to rotate the seat, but it is totally worth it.
