The Lippert Kwikee 39 Series # LC3724742 and 28 Series # LC3747453 single steps are pretty similar with just a few dimensional differences. Here are the dimensions:

Kwikee 39 Series
Entry height: 11"
Step dimensions: 23-3/4" wide x 10-3/8" deep
Mounting bracket dimensions: 24-3/4" wide x 4-1/4" tall x 12-1/8" deep
Drop/Rise: 7"

Kwikee 28 Series
Entry height: 9-3/8"
Step dimensions: 23-3/4" wide x 10-3/8" deep
Mounting bracket dimensions: 24-1/4" wide x 5-7/8" tall x 8-9/16" deep
Drop/Rise: 7"

If you compare the mounting bracket dimensions with what you currently have on your Freightliner you should be able to tell which one of these will work better as a replacement.
