Anybody know which direction the rear leaf springs go, center bolt to the rear shakel bolt dimension?

Center bolt to rear shackle bushing should be 31" and front should be 25" That's along the leaf curve not a straight line eye to bolt.

Short length, bolt to eye is front, long length, bolt to eye is rear.

Front bushing usually comes already pressed into spring eye. Rear eye is usually empty and bushing is put in with the shackle kit..

Hope that's what you were asking.

Thanks Bluebird!

No prob, I kinda wondered the same thing after I took the entire rear off the car and didn't pay attention to which way they were positioned. After I did the work on the housing and perches then moved to install the new springs I had a head scratching moment.
