Who else have problem with whitepunkonnitro?

^^^^
This and sending the guy unusable parts twice is what doesn't sit right by me.
Doesn't appear to be a mistake or an accident to me.
I am calling foul because I believe you knew better than to box any of this stuff up.
I agree the guy big time jumped the gun fileing the paypal claim before contacting you.
And he should have known more about what he was buying, but you could have prevented this
entire fiasco by being upright with the guy on the brackets. Then it becomes Once bitten twice shy on the retainer. You could have prevented this whole thing by not boxing these parts up.
I still believe you knew this going into it.
It isn't all this other guys fault. He was counting on you same as you were counting on his payment.

Look, as I said before regarding the brackets. There is no way to know his intent with the parts unless he tells me. I sell parts to guys all the time, who are going to use them in a non stock application. They cut, grind, weld and chop all sorts of parts to work in all sorts of ways . it's called Hot Rodding.
I TOLD him up front they were from a C Body! He obviously agreed because he sent the money. Is it my fault that he didn't spend five minutes researching the interchange?
I gave him no argument, and a a quick refund!
Robbing some guy from Virginia of $50 bucks for some caliper brackets he can't use is not the kind of thing I'm known for.
The retainer? Honest to God, I missed the crack because I didn't have my glasses on. I screwed up .. I admit it. I have another sitting 50 feet away from me right now that would be in the mail RIGHT NOW if he had just messaged me.
He only got the part this afternoon! He opened the package, saw the crack, filed the claim and started this thread!
This guy is obviously a loose cannon!..and for some reason that I can't fathom, you are aligning yourself with him.
He filed a claim asking for a refund instead of asking me directly for a refund. He can get his money back via the source he requested it from.
Seems pretty straight forward to me
