As far as buying 2-3 different parts to achieve a purpose - what makes you any different then anyone else That's what swap meets are for - sell the extras - but, of course, at a loss.

One item you may need to add to the LED lights wiring assemblies is either a 'special electronic' $35 flasher or a $5 resistor in each circuit. The LEDs do not draw enough current to activate a standard flasher. Take a look here http://www.watsons-streetworks.com/h...aillights.html

For possibly using tubing as a conduit, McMaster Carr (http://www.mcmaster.com/) sells lengths of SS and have a fairly good selection of clamps. Type in SS TUBING on their search function in the LH column. I wouldn't spoil a good paint job if I could mechanically clamp an item by drilling and tapping a small hole.
