SOOOOOOOO I ordered a new landing leg casting to go on my M416 trailer. I put it on and the casting does not reach the spring hold pin. So Is my casting for my trailer an M100? When i first bolted the tongue to the trailer i noticed the casting only had one provision for the lunette ring, where most m416s had two spots to put the lunnette. I "Assumed" it was something to do with being an M416B1 Marine trailer What do you think?
