Bucket to 60/40 Bench seat Swap?

I have a 98 with bucket seats. A few years ago i wanted to do this swap so found a guy who was giving away his 60/40 bench, but i recall it was missing the middle seatbelt and they were in rough shape, so i ended up throwing it away.

I'm considering doing this swap again so my dog has more room in the front. The passenger seat would remain the same, but for the driver 60 section is it a plug and play? Or do i need to drill/bolt in the seatbelt for the bench seat somewhere?

What I'm looking for (located in BC if anyone is reading this and has one):

 

Good info/pix from my swap
