i didnt get a ton of help and i really just need to verify where to cut the bed and the best way to shorten the frame.

here they cut the frame right behind the cab(anything wrong with this?)

whereass in this article they cut 6" out of rear section and 12" out of front section. 18" total.

so my question is what is the proper way to do this? cut under cab or behind cab? is measuring 83/4" from front stake pocket and cutting out 12" from bed and measuring 83/4 from rear stake pocket and cutting out 8" the correct way to do it? (this is something ive decided to do so please no input on how i shouldnt do it or i am ruining a LWB truck)


any help appreciated

thank you
