Published Front Frame Rail Width Dimensions

I am going to court over a damaged RMS AlterKtion front end I purchased on eBay. One of the shock towers was bent inward preventing the cross-member from fitting up around the frame rails. The factory AlterKtion is 34 3/4" wide, my bent unit is 34 1/4".

Does anyone have or know where I can get some printed documentation that show the dimensioned frame rail width for a 67' to 76' A-body?

Thanks.
