Call these boys here & ask for Rusty or Buster. Rusty is the owner & Buster builds the springs.
Buster can take your front stockers & positive arch them w/ an add a leaf & you will be happy.
Rusty's dad was doing work for me almost 40 yrs ago & NEVER had a bad spring from them.
Tell them Andy in Kosciusko told you to call.
