i have a 31 model a frame with a 40 ford front axle, the spring is a little wider than the crossmember to let it roll back to 7 degrees. which spring do i need to buy and where do i get it to run this front end under a model a frame full fendered truck ?
check out page four. Has some good info on spring lengths vs. perch position/shackles etc. http://www.posiesrodsandcustoms.com/images/pages115.pdf
