that is true, its a complete unit with the frame rails right back to somewhere just under the driver's seat, where it slips together with the rear section of the frame and is welded there. there are lots of builds that have used the s10 frame as a swap and to get the wheel base correct they cut that weld and slip the frame together some or they slip the frame apart some and then square it all up and weld it back together like factory. the 60-66 and the 73-87 trucks have a bolt in front cross member. not sure about the 67-72 trucks. the wms dimension is usually too wide. there is a fella on here that took tge 73-87 cross member and narrowed it. it was a 1 ton unit I think. there are some who have used the front suspension from a ford crown victoria as it is a bolt in affair. not sure of the wms dimension.
