to answer why the tow points are angled.. it helps when being pulled out.. not everyone can get pulled out straight and it causes less stress that way, you can still add d-rings.... if you can make them all day long for $320 then you should do it.. cause i would think you could make good money selling a good bumper for that cheap
sorry at work and its test night so had to stop and come back to this.. we are making pies tonight
also the guy that makes them has this to say...Mine are all 1/4" plate, the mainland one is 3/16". I can do one for a little less if I don't do the lights or loops.
