Its worthless without callouts and pics.
I agree. I have a lot to do with classic small fords, which is a similar small market. Personally, I give the company / person a chance to explain, otherwise I post about it on a forum, explaining what I ordered and why I wasn't happy (and i also make sure I post my positive experiences, because good vendors dererve more buisiness). I read similar reviews before making a purchace.
I think too many people are reluctant to post negative feedback for someone (and name them). As long as you are honest and tell the story how it hapened then you are helping the consumer (and in a round about way helping the vendor to realise their ssues). If I sold poop I would expect to be named and shamed.
Sure it is hard to make every part fit every combination, and when this happens (because I have random parts fitted) I accept it. but when I get a part that is just plain poop...
