The bulkhead will just bolt to the floor pan something like this. I will drill holes on the lows of the pan.
Here are my scribe lines on the front of the bed side. One for cutting and one for tipping over the edge.
I will tip the edge over just like the factory did here.
If I wanted to, I could just weld the bed side back together right at the edge. But I don't want to burn the paint if I don't have to.
Once I cut the extra material off, I started to tip over the inner panel. Again no welding here.
And started to tip over the outer bed skin.
With the inner panel fully tipped, I slid the end cap in place to see my progress.
Test fit is looking good. I just need to complete tipping the outer skin to the end cap, spot weld back together and add the front bed pocket to finish up this corner.
100% of the original paint save and 17' of weld avoided so far.
