The rod to use is a 7018...grind out the crack and fill it in with a vertical up...if you grind it...I'll stop by with my truck and weld it...n/c....

There is a rivet on the front of the motor saddle that will be loose/missing as well if it's bad enough to crack. I welded mine, pulled the loose rivet, oversized and bolted it, then gusseted the frame and it still cracked again in the middle of the box. More welding/ gusseting ect and this time built a big ass bumper that was very structurally integral. All in all, when the wife asked me one day what I was doing, and I told her that I was welding the frame again, she wouldn't drive in it again. I am a profesional welder/fabricator with over 20yrs in the trade, and I'm telling you, it's almost hopeless. A 1990 f150, sorry to say, is not woth much and probably not worth the effort. Sell her for parts and start something else. Sorry dude..
