Need measurements for weld in frame connectors

[troy.70R/T]

I am working on installing some U.S Car Tool frame connectors and need a measurement just to be sure before I weld them in or before I grind to much material off of them. I would like a measurement for both sides. I would like a measurement from the side of the welded in frame connector to the edge of the torsion bar hub that is welded on to the frame (Trans crossmember frame). I would really appreciate the help. My inner rockers are a little bit bent from installing new outer rockers so I really can't get an accurate measurement this way. Thanks for any help.
