You might also try the dealer you got your trailer from. EZ Loader maintains a pretty good inventory to service their stocking dealers. The dealer should be able to do a quick phone order and have the needed trailer parts in just a day or two. I'm very partial to them since I've run them for the last 22 years... My first one went 350,000 miles before a snapped axle diamonded out the frame and sent it to the bone yard. My current one is somewhere near 110,000 miles at present (and I just clocked another 200 miles on it today...).
