10 Andrew Stainless Tower Standoff Kits 30848-4 - eBay (item 270179383160 end time Apr-19-08 23:24:56 PDT)


a couple of hints when using a standoff... you will have to grind a little off the inside edges to clear the bolts from the engine. Trim the engine bolts about .75" . For the stainless steel clamp, use .5 x 4" heat shrink, it will cover the clamp and protect the frame a little. If you crank too tight on the clamp it will strip.
