  • Frame / Springs: Are Rear Springs for 1961-1963 sedans interchangeable?

    Some time this year I'll be looking for a 1961 or 1962 two door sedan and am interested as to the fit of 1963 Cruiser rear springs as being a possible replacement if needed.

    What say you...

    I do not know about the springs, But I have a 1961 2 door hardtop here that needs a new home. It has the 259 and flightomatic. I was going to work on it for myself, but now I am up to my neck in trucks, so I could use the space and the cash for those projects.

      I'll be in the market for a sedan as opposed to hardtop and preferably one that does not have a drivetrain as I have in my possesion a very low mileage 289 out of a very rusty '63 Cruiser. I just want it as a "fun" car...

      good luck in finding the '62 a good home!

        To answer your question...interchangeable? Not exactly. Beginning with 1962 Lark models, the rear spring center bolt was moved rearward by 1/2” - thereby increasing the wheelbase of 1962 models by 1/2”. They are the same overall length, but you would always want to change them in pairs if you were to install ‘62 and later rear springs in ‘59 - ‘61 Lark models.

          I don't expect you will have any Fit problems Y9 Body to F4 , it is just the Spring Rate that will be stiffer being designed for a Longer W/B, heavier Car, and I don't think it is going to raise the rear much, but that helps the "Loaded Height" to be more reasonable.

          We installed Used '63 Wagonaire rear springs with 5 leaves, in a '63 Cruiser and it raised the rear ride height maybe 1 -2 inches empty, but nice and level instead of sagging with rear seat passengers.

            when you buy new leaf springs from Eaton or other, do they deliver with bushings installed ???

              I think that is what I'm looking for and maybe I should also limit my choice of of a two door sedan to the '62 models only. The springs on the '63 rusty, (55K), Cruiser still have a nice curve despite the trunk being loaded and stuff on the rear seat.

              Since the '62 two door sedan will be a "fun" car should I be lucky enough to find one I'll also be looking to install a heavier front sway bar and rear stabilizer. I do have access to to the earlier sedan rear bars that were standard equipment for President cars. I also have a set of early spring brackets with the tab to secure those stabilizers but that would present an issue as to what shocks to use...

                That's exactly the result that I am seeking.

                Before I abandoned the '55 Prez State sedan project, I considered springs for a '55 station wagon but all that is off the table now.

                  That's a very good thing Grumpy, (James) because there is NO Way those '55 Springs would fit!

                  I believe it was 1957 that the Springs changed to asymmetrical mount points, ---the Diff. is Off-Center forward on the Springs, and the Length is Longer.

                    I think that you misunderstood about the '55 station wagon springs that would have been intended to replace the "re-arched" sedan springs that I had purchased from the old Standard Surplus which were worse than the springs that were on the car. Wouldn't the springs from a station wagon (1955) fit a '55 long wheel base sedan?

                    Since I've now decided on a '62 two door sedan for a "fun" car I am assuming that station wagon springs from a '62/63 would fit as well...
