converting bench to captain chairs in previa?

im interested in buying a previa, and have found a couple. problem is, i would like the captains chairs in the middle row as opposed to the bench. is it possible to convert the bench to captains chairs? if so, what's required and how hard is it?
  or should i just keep waiting to find one with captains chairs? i would have posted this in the van section..but im not allowed to yet..=P thanks for any help in advance!

i am not sure what parts u will require, most likey everything include the bolt to anchor to the floor....because i saw my buddy convert one.....he had to drill new holes to the floor just to re-anchor the captain seat!

really? is your buddy on here? does he have pix of the build? i am very interested to know what is involved, so i know whether i should just opt for the bench and convert it, or take my time and find a captains chairs.

also..cuz another thing im planning to do is convert my rear bench into captains chairs too..so i would like to know some kind of process
