Forget about it. that's an easy job and those closers haven't changed
much in that time. it requires no tools to replace but a screwdriver.

Having replaced a few closers in my day, I'm going to wager that it is
going to take more than just a screwdriver to replace. I'll be very
surprised if the holes on either the jamb bracket or door bracket match
the holes on the existing unit. At a minimum, you're going to need a
drill. If you are lucky, the location of the holes will be different
enough that you won't end up overlapping half a hole. I hate when that
happens!

I would take the old one with me just to be safe..maybe you'll get
lucky and find one that lines up perfectly. Depending on the type of
door you have, you might be able to relocate the closer to the top or
the middle of the door if the old holes become an issue.

I need to replace my old pneumatic closer ( over 25 years ) for my
storm door. Any suggestions? Would like to pick it up tomorrow am at
loews. Should I take the old one with me? I'm sure they have advanced
since and don't look exactly like mine does now.
