The epoxy pads I had injected into the wheel pants last night were cured, so I popped off the front half of the pants and built up an epoxy pad for the axle extension. This gives the axle extension a good solid interface to the wheel pant. I just had to wrap the extension in packaging tape and wax up the screw with some turtle wax, and then I slopped in some flox. I also cleaned up the wheel pant bracket pads where the epoxy had squirted out more than it needed to.
Then it was on to fitting the right side wheel pant. I followed the same procedure as the left, but this time managed not to smash any more fingers. By the end of the night, I had the pant aligned and the epoxy injected.
Ed, Curious as to where you got the aftermarket axle extensions and why you used them instead of the stock ones from the kit.
