I seem to remember someone posting how they built their own trailer guide ons- the tall pvc pipe type.<br /><br />What type of clamps and u-bolts did you use? I have 3"W x 4" H trailer- shorelander. Where did you purchase the clamps and u-bolts?<br /><br />I got all the other parts, just need to order the hardware. thanks.<br /><br />Joe
