Avoidance Alert
Sounds like both parties share a little communication breakdown blame but I think I'd have to lean toward Dartnut. I mean, what is his motivation? To work a scam for $20.00? What leverage does he have to get it? Sounds like he's the one out money, not J4R3D. If the package arrived damaged/incomplete, file a claim with the shipper. A few questions remain....why were there no photos exchanged and a clear description of what was needed before ANYTHING was shipped? Shipping uneeded parts back and forth just makes money for the shipper. Why weren't the brackets and linkage bolted to the booster so they wouldn't get away? Now if you two can shake tires and play nice you may be able to work together to figure out what happened to the missing parts! :-)
