In 2004 I installed Bilstien shocks and a Helwig rear sway bar to my 1993 Roadtrek 22ft. Last week a found that the sway bar lost the 2 bolts that attached one side to the under carriage. I cant find the installation instructions and for the life of me I cant figure out how I got the bolts inside the box frame channel. There is no opening. Also looking at it I would think it would work better if the end of the outside bars faced backward instead of foreword. Can anyone help?
