OK I have an 83 pickup and the RUF has already been done and from what I have read. When the rears are moved to the front it should be a 3 pack with an add-a-leaf. Well, it isn't ... and I am not a huge fan of having flat ass springs. And before I can put my new hoops on I need to know where I am sitting. Long story short after loads of hunting and finding some things but not wanting to waste time and money on guessing which is the right part. What Add-a-leaf should be used on the RUF leaf spring set up?
