don i took photos of the belt guard, but my computer won't import them right now, i said i put in a louvered pannel but what i put in has 56 1/2 in square holes 8 across 7 high starting right behind the pto where the guard is single thickness. it looks factory, 100% mig welded , & metal finished ,primed & painted. i have enough of this metal to do at least 30 belt guards. i have a 516, & 2 520 s that are curently not running & i am going to put the pannel in these guards,and if there is interest i will sell them on an exchange basic to help out members who dont have my fabrication skills. let me know if any one is interested, Jay
