Hey folks,I've been looking for some guide ons for my 1990 escort trailer. (bunks, not rollers) Where can I buy them at? I don't want to order anything off the net unless I have to. I have a galvanised trailer and the boat is wider than than the trailer by a good foot or two. I don't have any welding equipment. Should I be looking at a bolt-on kit? (I've been told it's not good to weld to galvanized) If it's a windy day my boat always ends up on the trailer crooked, And I have to loosen up the winch and back it down in to where it floats off the bunks, then bring it back in and check it. I'm hoping the guides would solve that problem.
