Man - I can't believe you still have that many at the yard! There's nothing that old left in the yards around here! Unfortunately, I don't think the part would survive shipping - nevermind what it might cost to ship something that big.
All set on the bumpers - mine are in decent shape and just need a good cleaning/polish and they'll be good enough. Remember - this van needs to stay my daily driver so I can't make it too nice or I won't want to drive it like all my other cars....LOL!!!
