| CAV - Getting the Horsepower to the Ground - Part VI Finally, the top cap was added and bolted in place. The cap basically completes an enclosure around the neoprene so that it can only compress and cannot squirt out the sides. I suppose it also protects the neoprene from road chemicals, UV rays, and STDs. 3/8 inch diameter bolts and bolt holes were used in the bottom shelf and the top cap. 5/8 inch holes were used in the U-bracket to allow for mis-alignment and so that it could squirm around without any metal contact. |
