Been 4 linking this old rain gutter ranger. Running my 60inch links. And 2.5co and gonna have 3.0 bypass. Did a c notch and kept existing backhalf. Truck has a lsa supercharged 6.0l with th400. Long bed action too.
I weld them full length one pass then do weld next to it full length all the way around. Nm o warping because it's all equally hot at almost same time. Also they are tapered wider at heim than at bar so that helps too.
