Sorry to be the bearer of bad news guys (and girls) but you may have to actually pick up the phone and call one of the wreckers.
I come from inside sales - if someone wants something bad enough, they'll call.
Have the part numbers for the items you want beside you - phone a wrecker, get their email (personal if possible - most of the time the wrecker has a main inbox and then employee specific ones) and then email the person you spoke with the pictures of the exact item(s) you want.
Definitely kickin' it
old school.
