I was given a Weider 560 bench/squat/pull down unit for Cristmas by my daughter and her boyfriend. There was a square bushing missing from the unit. At this point I had the set mostly assembled. I had also already hauled off one of the large boxes. I contacted Weider. I was informed that this part was not in stock and it would probably be the end of march before they were back in the warehouse. Sams Club, were they bought the unit were sold out and could not help me. I have sat here looking at that thing for six weeks now. If anyone has any suggestions that might help resolve this issue, please let me know. One last statement. When it comes to some equipment, its Buyer Beware.
