I have a 1929 model A roadster I have had it for a while .It has a 9.3 olds/pont rear.It rides hard the shackles and spring are up against the rear end instead of 45 degree. I went to check the spring leaves to see how many are there. There are only one.When I put the car on jack stands and put a jack under the rear I can get the spring shackles to a 45 degree position.I took the spring out it measures 42 1/2 inches with the spring perches at 48. Information I have foundinformation that said take spring width add 5 inches to it and set the perches which is real close to what I have.I think the single stock leaf is to soft. I have a extra front leaf spring complete can I use leafs off of to try or do anyone have a different Idea?
Thank You



spring 42 1/2 + 5 =47 1/2 mounts on rear End 48 inches
