Will gen 2 seats fit in a gen 1?

I'm looking to replace my seats with something newer. I have buckets that are worn and need replacing. I see some 2nd gen stuff on eBay along with Toyota OEM seats. Anything of the age of my truck are going to be worn too is the reason for wanting newer. Anybody? I know it will need custom rail mounts, but is it doable? Looking for gray if anyone has something. Money is not my first concern, OEM looks and comfort are.
If I could buy OEM replacement (new) I would.

 

I think it'd be a little too wide. Why not reupholster them? Or maybe get nice katskinz?

 

I've seen some people make it work. However, they are Too big for a access cab setup, while retaining rear seat access.
