Hello, anyone know what part number have plastic covers from picture below?

 

Nobody? :(

 

Try searching for bed rails on ebay, and try to find something similar. Summit also sells them.

 

They are "EDGE" rails. Found it here:

Still need help with part numbers for short bed version

 

As far as I know, the Ranger only came with two bed lengths. Long, and normal. As a matter of fact, I've never even seen a Ranger (in picture or otherwise) with anything else but the standard size bed.

Normally it's a problem of finding a bed topper/cover that will fit the stepside bed, which is substantially narrower than it's flatsided counterpart. For bedrails though this makes no difference as the overall length is the same.

 

Good to know, I was thinking that there are two types of bed lengths.
