I wish...Those are easy. This is one of the twisted ones that are at the top of the opening. These can toss you off a ladder if not done correctly. I have installed several of the long springs over the years and never had any problems.Patrick -- sorry to hear about the garage door. If you are talking about the long springs on the sides of the door - I have replaced them on another house back 15, or so, years back. Not exactly easy to do - and I can't remember how I did it - I think the wife helped hold something while I stretched the spring.
Save yourself some money ... might be some cussing involved?
