replace rear seats in 2002 Tundrac access cab

[buba1]

Can these seats (in a 2002 Tundra access cab) be replaced with something else like for example seats from a 2004 double cab. I am looking to make them more comfortable, basically. I already did the mod with the bushlinks.
Just trying to find out if the bolt placement pattern would match with another seat and also where would I buy/order these seats?
Thanks
