good question. about the only way to know would be to have the rim to inspect first hand. i would guess there is more thin areas in addition to the 2 pin holes. on the other hand, my experience, anything can be repaired, if one throws enough money at it. i guess it could be worth the gamble to buy the rim, take it to a competent welder and see what he says. i don't have any first hand experience saving rusty rims.....
