Hey Shellology
You have done your homework on this! I checked out the website at
http://www.lowcosttrailersupplies.com/ and they look to have a few other options as well as the ones you bought. Great resource for a difficult problem to solve. The Advanced Design 3/4 ton and up 'bolts are awesome but a little on the problematic side in some areas. A solution like this is welcome and helpful to everyone. Thanks!
