</font><font color="blue" class="small">( As you won't be able to turn the nut on the lift pin with such a limited space, make sure you get a lift pin with adequate space to grip with a wrench. )</font>
I'm the guy that asked about this originally. This is refering to the lower 3-point lift pins that go in the hole on the end of your box beam.
I was thinking the same thing, even with space to fit a wrench in, you might not have space to actually turn the nut.
However, there _are_ pins available with 2 nuts, so you can just hold the inner one, and tighten the outer one. Might have to look at a few suppliers, but you will find them.
I'd not be comfortable welding them, they might be hardened; and a nut might hold the heavy stress better than a weld joint - well, any how with _my_ weling skills. /forums/images/graemlins/wink.gif
