Thanks guys . I hope to get a chance to call and talk to someone next week before I place a big restocking order.
I put that bar on my Craftsman/Poulan 3400 today. Turned out I had to grind down the paint inside the bar stud slot to get the bar on. It would go over the threads on the bar studs, but not over the shoulder where the bar rides. If they had masked off the inside of that slot before powder coating the bar, it might have gone right on, but as it was I had to take the dremel to that slot so the bar would slide on.
Just a heads-up.
