I ordered similar from ATP only one front arm was delivered & had obviously been crudely taped back up in the bag & rejected by somebody else
I wasn`t happy with the the arm I did get , presumably why somebody else rejected it.
At the time ECP was supplying Lemforder parts, which were miles better in build quality.
So I bought all I needed from them in the end.
Although I don`t think TB is a lemforder fanboy & might dispute the above statement
I paid via Paypal for the ATP order & filed a dispute with Ebay for a refund.
I really think you need to see what you`re buying over a counter Webby, anyway that`s what I prefer these days.
