Customs Ranchero Seat Questions

I am looking for a 1957 Ranchero Bench Seat. Does a 58 or 59 bolt in a 57? I have located a 59 just don't know if it uses the same track. Floors are perfect and I don't want to drill new holes in them if possible.
Thank
Matt

 

I tried one from a 59 and it bolted right into my 57. I ended up using a 4 door bench seat out of a 57 though because it does not have the split back. It was very easy to make it flip forward like a 2 door seat.

 

Perfect!! Thanks for the info.
