So I take the rear leaf springs from the '55 Plymouth into Texas Springs in Amarillo, Texas to have'em de-arced 3" I throw 'em up on the bench and the old guy says " Mopar, early or mid 50's" Damn, so far so good! We look'em over real close and he finds a cracked spring. I verifed the crack. Good eye old man. He is gonna fix me up with a new set of springs in about a week. Just wanted to say it's nice to find a blacksmith who knows what he's talking about. Looking forward to a lower ride!
