73 coronet wagon parts interchange

[tanis4457]

I'm new to B bodies and am going to be picking up a 73 coronet wagon soon and I was wondering what parts interchange on these cars. I'd like to replace some of the suspension parts on the car and was wondering, when I'm looking up parts on jegs etc.. do torsion bars, leaf springs, strut rods etc.. interchange with earlier years or did dodge start a new line of parts for these 73+ up cars? thanks

73 and up was a different suspension setup. You may see this called an "ISO" or "ISO-K" suspension as you read through posts on here. I would suggest that you swap the k-member biscuits to poly or a solid spacer, and eliminate the iso bushings mounting the rear axle to improve handling. The iso setup was designed to eliminate road noise and vibration, making the handling more "floaty." Torsion bars are longer but available, I believe through firm feel. They also have a rear axle iso-elimination kit.
