"V8'ing" a Slant K member

Haven't some folks just had to modify the drivers side saddle of a spool mount /6 K frame? If I remember correctly, the passenger side saddle on a slant spool mount k frame is the same as a V8 spool mount k frame. Drivers side on a spool mount slant is taller than a V8, and you just have to cut X amount off of it, and drill a new hole where the V8 lines up level. I remember one person that did this....so I'll try to dig up the thread and post the numbers of the posts in it that relate to this topic.
