Sway Bar and Steering Stabilizer Questions on 1999 Shasta

As posted earlier, I used the existing holes in the frame to mount the Helwig. The angle was off a little, but talking to Helwig engineer, said I was within specs. If you need to drill new holes, will need a good 1/2 right angle drill to get in there. Just be careful not to pinch the fuel line. Took a while for me to figure out why the thing wouldn't crank:(. This on a 97 e350.
