My Mazdas backhalfed its not hard, if u can fab, i just took some measurements then busted out the torch and cut the ass end off, i wouldn't trust a hobart 125 flux welder to do any kind of frame work though, heat and penetration is a big deal if u dont wanna loose the ass end of ur truck, Mines not real crazy or anything but i'll post a pic and u can get an idea, i've redid alot of it though since this pic...
