1966 Mustang Get Rid Of Sag, Longer Rear Shackles?
Lots of nice progress is happening with the 66 mustang. I'm planning on getting new rear leafs, but it won't be for a month or two. I took out the rear shackle as a template, but I want to make longer rear shackles to raise the rear end to take out the sag and even raise the rear end say 1" max.
Now, the question lies, if I make the shackle say 1.5" longer then stock (3/4 to rid sag and 3/4 to raise up), would that be the actual result? Or would it be less since the geometry of the spring would be diff. The only reason I ask this question, is b/c I remember 4x4s doing this, and (if i remember correctly) it was never a 1:1 ratio.
Any input? Anybody have a set of aftermarket ones that take up sag or raise it a little?
