I can try to find some pictures for you, I've done a couple dozen of these frames.
I've had them just cracked or completely severed and bought some DOM tubing to work with. I wrap that whole tube around to the back and tie that in to my gusset. I drill 10mm holes in the wrap, staggered throughout so that I can weld the wrap to the original Honda metal as well. I gusset the lower subrframe triangle and the upper subframe triangle and I leave them long enough that I can weld them to my full frame wrap. Once I wrap it and weld them all together they are super strong and I haven't had one crack again. I usually use 3/32 or .09375 steel for the gussets and thickness of the DOM tubing.
The best frame they made was in early to mid 1986 when Honda actually did a half wrap around the backside. I have 1 frame that I run and I haven't broke that one yet so it certainly helped. They made at least 3 versions of the 350X frame.
