has anyone used the s-10 extended cab frame for the 51 short bed swap? I have an 87 s-10 ext cab 4x4 frame and body looking to be part of something better in life. I have done research and relize that this frame is longer and will need to be shortened. I have the ability to cut and weld this part of the project. Hoping that someone has done one that can shed some light on any problems that we will encounter.
