Bench Seat

I have a 66 Chevy II Nova (4 dr) with bench seat. The seat is trashed, including the frame/springs, etc...

The other day I saw a good deal on a bench seat locally...it said it would fit a 66 Chevelle or El Camino. Would this work in my Nova?

I'm not sure how wide the Chevelles or El Caminos are....

Thanks in advance,

Steve
