Product review (4 stars): Light blue spring = blue = full size , Dark blue spring = black = compact
The parts were an exact fit for my washer.  The only issue that I had was with the springs. The instructions did not match the parts that were included.  My original (full size) unit had a medium blue spring.  The kit came with a dark blue spring pre-installed and a light blue spring as an alternate.  The instructions stated that the blue spring was for full sized washers, and the black one was for compacts. It was also stated that the pre-installed spring was for full size.

It turns out that the pre-installed spring (dark blue) was the one for compact washers.  The light blue spring is the one I needed for my full size washer.
