I bought a bulldog swivel jack with a weld-on L shaped bracket. The bracket has 4 small bumps on the plate that prevent the plate from fitting flat against the tongue. It stands off about 1/8" from the tongue surface. There were no instructions on how it should be welded on. I sent them an e-mail about getting some instructions but have not received an answer yet. The trailer coupler I bought had specific instructions on how it should be welded so I assumed the jack should have also. Anyone have any experience or knowledge of the proper way these should be welded on. I have the Model TWS
151 DS which has a 2000# rating. The trailer is 6' x 12' with a 3500# axle and the tongue is a 4" channel 50deg A-Frame.- posted
