Great link! I bookmarked it. My MII kit was a TCI as well, hub-to-hub. I didn't have a problem with the length of the boxing plates that came with it, they were plenty long. I did have to trim the lower frame flange a bit in order for the plates to fit flush on the frame. I beveled all edges of the plates, as well as the frame edges, to get maximum penetration. I think that's a critical step to ensuring a strong weldment. I didn't 'dress' my welds at all, left them as-is. I didn't care what those welds look like (mine's not a show truck, just a weekend driver), I rather have as much weld strength as possible. I also welded close-off plates to the open ends of the cross-member, for added rigidity.

Thanks for the link, I'll keep checking it for progress. Its an excellent how-to for folks looking to tackle one of these builds.
