Mike - ping me off line if you need any help. Frankly, its really easy to do. Hardest part for me was finding the extra U-bolts in the right size!! Any good hardware store (i.e., not HD) should have them. Some tips for your install:
-- I replaced the wingnuts that came with the U-bolts on the brace with nylon insert lock nuts.
-- Cutting the brace was easy with a dremel tool. Since its made out of aluminum, its easy to cut. A hacksaw would have done it too.
-- While at HD, pick up a couple of locking pin clips. When you slide the PVC over the ends of the ladder brace, you'll want to drill a hole through the PVC and ladder brace so you can insert a locking pin. Something like this:
This keeps the PVC pipe on in case you hit a bump or pothole on the road (don't ask how I know this is necessary!).
-- As for the light kit, easy (and cheaper) way to go is to but some PVC end caps (you'll want them for a finished look any way) and mount the pedestal type lights on them from Advance Auto (or Pep Boys or Autozone or . . .).
That's about it. Again, feel free to ping me direct if you have any questions.
