67-72 chevy crew cabs

[atvpro]

Yes I did lengthen the frame using the 1/2 burb frame and 1/2 pick up frame. The way that I cut both you end up cutting off a little extra on both frames, that way you are not putting a section in I did a z joint with a backing plate. You absolutely can not tell that I lengthened the frame by looking at it. The frame extension was exactly 3 feet and yes I am doing this with an 8' bed. Both are 3/4 ton.I moved the center drive shaft support member forward and basically split the difference between the two drive shafts so they are equal lengthens. The pics I posted do not reflect the finish product, I am about to pull the cab back off I'll snap some pics and show you, including detail pictures of the reinforcement inside the frame.
