the sand trick aint a trick lol it WORKS and it's the best way to insure u do it right and dimond plate meaning finding a way to bend it so it's covering the beams and protecting ur lower engine as well a member did it i am trying to find a pic of it right now
that would look good to but expensive to make the tubing aint cheap and to have it bent will take someone who knows exactly what they are doing. i tip for u to know is if u fill the tubes with sand before bending them and tape the ends keeping the sand in there the tubes will bend the right way if u do not the tubes will crease and look like shit and u will have to try and bend them again with a new tube.
if u can find some dimeond plate and bend it into a skid plate paint it black dril holes in it where there are holes in ur frame and bam ur done and it will look good
