I would be very cautions with disc brakes on the drive and drum on the steer. Having more braking action on the drive is what causes you to switch ends on slick pavement. I was a licensed salvage dealer for many years. I stayed away from anything that had a fire. Fire distorts things that you would never believe it could distort.
fire was in the engine compartment. very little cab damage and no damage further back. had a 40 gallon gas tank that was undamaged. (I kept that). getting good and useful info from you guys. thanks. keep it coming.
