How to Move Shackles in 3"

Here's a couple pictures. -My right angle grinder just showed up. Honey Do list gets priority today though.

Here's a shot of a finished hole. (Drivers side, outside of frame rail.) You can see the tab that is part of the original shackle bracket and how it is welded to the main frame rail. That's where the USCT won't fit. I'll add a picture showing how it fits now. The hole to the right of the new hole is the hole that is usually used, at least from my research. You can see part of the threaded insert in that hole. That would be hard to open up for the sleeve.

This is a shot of the spare tire well side (driver side). Just the rough hole is drilled (on an angle). You can see the well and how close it is. I'll also include a shot or two of the sleeve.

I'll take more shots as I finish up. I don't know if I'll show my booger welds though. :)
