maybe we discussed this but in case we didnt, there is a factory joint in the s10 frames, all the front sections are the same regardless of wheelbase and the rear sections are long or short to make the different wheelbase, the splice is under the door. you can grind out the welds, slide it apart, cut off the section, and slide it back together and weld it up. having it slide in and out makes it really easy to get it square and strong, unlike a butt weld
thats if you want to shorten it
