I'll always be a professional grinder and amateur welder. I get too little practice although my results improved markedly when I started wearing my reading glasses under my helmet and lightened up the dimming function. Night and day! Literally.
I bolted the driver's seat base up to the tracks and installed the seat cover on the upper section.
Dropped the whole thing in the truck. Good angle, firm seat, more leg room than I need, more headroom, and it reclines way back. Enough forward seat travel to let Legz drive her shift. I am hopeful that the center folding seat will be far enough back to allow the dog house to come out easily. We'll see...
Recall the factory seat went no further back than the cab side of the box wall.
