Hopefully it will work out for you, good luck. I had the same thing happen to me, my frame was perfect and I decided to weld in some 1/4" plate steel gussets on my front kick-up and it ended up bending my one side up 1/4". I heated the gusset with a torch and cooled it with water and it bent it 1/8" at a time, so after two tries it was back to normal. I really didn't want to cut that front end off but I wasn't gonna leave it like that.
