Pictures is what would really help.

I'm doing a double triangulated 4 link setup and have been thinking about how to make the crossmember/mounts for the upper and lower links at the frame (yj frame). I could sit here and eventually figure something out, but I figure there are so many creative smart guys here I might be able to snag some ideas....ie: copy you :D

This is hardly rocket science
