Its the "Been there, done that" articles on all things Ranger, very handy link
Look in the "Interior Electronics & Upholstery" section, and then in Seats
There are also links at the bottom of the article with more seat info
If there are no seats and no frames in you 1995 then you should at least get the frames, that's the part that bolts to the floor and slides forward and back
The seat bolts to the frame, up to about 2001, then Ford starting welding the seat to the frame, but it can be cut off and other seats bolted to frame
Regular cab and extended cab frames were different in how they bolt to the floor of the cab
Wrecking yards will sell trashed seats with frames cheap, that way you get all the bolts and "seat belt" parts as well if needed
Then you can use any seat you like bolted to those frames, or maybe you will find nice seats with frames
