The left inner fender mods are completed. I welded in the curved patches that wrap around the intercooler pipe. Still needs to be ground smooth, but I need to reinstall the front suspension and check tire clearance before I finish the welds off- might need further mods.

*Update*
After setting the car on the ground, the left tire came a bit too close to the inner fender than I liked, so I trimmed the patch a bit and rewelded everything back in. The picture shows the clearance now, with the wheel turned to the right and the suspension collapsed- looks like enough clearance now.
