The guy in this video uses a method similar to the one mentioned above but he angles the rear cut which is supposed to make the body line easier to match up. The video shows how to layout the cut template with masking tape on the rear section. After reading the treads and watching several videos I purchased bedsides from form LMC because they offered free shipping with any purchase over $1000. The two bedsides were $998 so i added a cheap part to get the free shipping. I was impressed with the bedsides but unfortunately UPS damaged them. LMC is shipping out another set but now they are back ordered. To me time is money and if I spent 20 + hours cutting , welding and body working bedsides I may as well buy a pair that are guaranteed to look good.
