88 D150

I just bought an 88 D150 and the previous owner had lowered the rear a couple of inches, so I'm trying to put it back to the correct ride height. I bought two new factory shackles, but am wondering which way they face? This is for the rear shackles. If somebody could post a picture of a stock set up, I'd appreciate it.

spring above hanger, cupped side of shackles face forward. Bolts in from inside, nuts on outside.

Ok, the cupped side was what I was wondering about. Thanks
