barely legal welding
+1y
We welded up some cylinders last month for a guy doing basicly the same thing you want to do. It was for a honda car. He wanted the cylinders notched and 2" 1/4"wall d.o.m. welded to the top, so he could run a poly bushing(like 4-links) we also shorten them some for clearence problems he had. I Tig welded the joints but you can Mig weld them and be fine, just pressure check it for leaks.
