This update will be about the repairs on the back of the cab (I had to do some internal rebuilding of the floor structure in order for it to notch around the driveshaft, but this post just shows an overview of the exterior work I did)
The before pic...Underneath all the previous body filler (visible from inside the cab) are patches & repairs that I've highlighted in red. It was deemed easier and better to fabricate a new cab corner to get rid of the previous patches plus the fact I had to lengthen the bottom of the cab corner to account for removing the running boards as I mentioned in the previous post.
Cab corner exterior trimmed out and ready to fit the new piece I had fabricated.
Fitting the cab corner. Note I also trimmed and installed a finished edge around the complete bottom of the cab corner. The big "notch" is allowing space for the exhaust eventually, the smaller "notch" is obviously to gain some clearance over the frame rail.
Tacking in the lower center portion of the cab. Another notch was needed here to allow clearance for the driveshaft when the air ride suspension was lowered.
The passenger side cab corner didn't require as large of a panel shaped, more so just needed to lengthen it to match the driver side. Here I've also begun planishing and finishing the welds on the passenger half of the cab.
