Never heard of a company having to have you call to confirm your info. Never. That is a red flag to me. Also you need to tell us who it is so that we know if it is one we commonly use for that type of item like CPP, POL, Classic, J. Carter, Speedway, Jeggs, Summit...........or some flunky place. There are all kinds of scenarios here but have not heard of one of those companies having mixed threads. If you used a funky place, they may be buying "send backs" and refurbishing. Someone ordered metric studs to fix a returned item.
Started with Pony Parts. They had the confirmation expectation and canceled my order. I then moved to Speedway. They sent me the two right side spindles and rotors with mix matched studs. I think this was a supplier issue. Speedway would have had no reason to to open the boxes to check this. Items came from CPP.
1. Having to call to confirm payment/address. Never heard of that. What is there to confirm? Did you not fill out something correctly? Completely? Why were you not "able" to call?
I paid for everything via card. I was charged on my account. Then order canceled and charges reversed.
2. Sending two right sides'. Super bad product marking system or bad order filler person.
I think was a CPP issue.
3. Installed mixed threaded studs. Very inexcusable and very dangerous. Never head of that either.
Agreed. I guess one of the metric sizes is super close to 7/16 x 20 cause you are able to thread it on a ways before it binds. And when it binds it binds softly at first like there is dirt on the threads so I put a 3/8 ratchet on it and started snugging it up. When I realized it was binding I tried to back it off and it turned backwards about 1/2 a turn and bound up tight breaking the studs off when I moved up to a 1/2 inch breaker bar.
