front suspension repair or not

[beautimus]

i wanted to ask for some advise here about my front suspension crossmember.
while cleaning it up for paint i discovered 4 different cracks on this thing.
the first 2 lie beneath the engine in the curved area on the front upper edge.
i am not to worried about those, i can find the ends of the cracks rather easily and i can mig those up and grind them smooth, no bigg deal , i think.
the second 2 are on the upper a arm supports. they do not lead to a bolt hole or a factory rivet, so i feel pretty confident that i can do a good weld on them.
the cracks are on the front edge only. pics are of these 2, i couldnt get the first 2 to photograph well.
the question is, should i repair this thing or just chunk it and get another cross member. opinions please..


thanks, tony
