I call them Year-None because not once have they ever had anything in stock that they advertised in their catalog that I needed.
Everything has always been on back order with no guarantee when it would be coming in.
Seems like they just order takers and are at the mercy of their suppliers.
I usually call around and find the item from another vendor/ supplier.
Too bad Summit don't carry much brand specific parts because I have had nothing but great experiences with summit and they almost always have everything they advertise in stock.
