I chopped a step side but it started out a shortbed...
The key to me was working from the step back except I chopped and channelled the steps too. But short or long bed side steps are the same, so the changes are all out back.

What I removed was from just behind the center pocket so they stayed the same. In your case I'd take out more than the 4" needed for my toyota...but only your tape measure will know for sure.
If you don't mess with the front half you dtill have mounting holes to help hold the fender in place while you drill the new holes in back.
Welding it was standard hit and run per MPandCs guidelines.
And I am assuming this isn't for a concourse restoration cause... your chopping a bed.


Give me ambiguity
or give me something else
