The Speedway kit came with instructions to trim the inner fender and bolt a mount to the top of the frame.
I opted to widen the stock holes by 1/16" and follow the stock routing. There seems to be plenty of clearance to the inner sidewalls with the wheels at both extentions.
Now that the hoses are installed, I could put the wheels on and get a final look at the stance with all the new parts. I am quite pleased with the look. It is sitting on jackstands under the axles, so this should be the final wheel heights.
