Help with K frame

phone crashed , that was my only camera. I realize this sucks , but imagine the ears for the spool mounts cut off almost flush with the rest of the frame then relocated and welded 3/4 inch rearward. The spread between the ears remains unchanged, just locates the mounting point to the rear by 3/4 inch from original position. I know I saw this procedure outlined somewhere, for installing a big block. I am just concerned that I''ll have to rework everything to stuff my small block.
