Overhead doesn't bother me at all cept when slag goes down a sleeve and you do the Oh **** dance :) But.. i had like 10" to work in and welding with my wrong hand and all that.. i didn't wanna jackstand the car knowing how much it flexes so i was under there at ride height.. all done though, til the drivers side :)
I will end up cleaning them a bit with a burr and seam sealing anyway
