A small 3/4" crack shouldn't be anything to get all concerned about IMO, I'd gas weld it without hesitation, or a mig should work fine-just put a good weld down that's hot enough so it isn't brittle, don't over grind the weld causing the basemetal to thin and it should be fine. Or you could section 1/4" out of the cracked area and make a filler out of 1/4" round stock welded in place then grind to shape. I agree a small backing properly brazed in place would add a lot of strength and would be more crack resistant than just welding the crack. 40 year old fender, is this car a 55?
