37 Terraplane Front Spring Shackles

I took the front axle off my 37 Terraplane. It appears the springs have been off the car before, a really long time ago, and may have been reassembled incorrectly. Each side has a short shackle and a long one, the long ones having a left hand thread on one side. The short ones have a right hand thread on both sides. The driver's side had the short shackle at the front, and the long one at the rear, the passenger side was the opposite. Was that correct? Or should each side be the same, and if so, short to front, or rear?
