Hi there!

Start by taking a look at our 81-023, 81-278, 81-279 or 81-282 rollers. Look over the dimensions for each and compare them to your original roller to see if any match what you need. 

A handy person from myrtle beach SC says:
The 81 - 282 roller is the exact one but inside the door what is the two holes at the top of the roller for one is threaded the large one is just a hole

The holes you're referring to are used for installation in some cases, but not all. It would depend on the door.

I saw a video with somebody who had to take and slide one of the channels back so that he could pry the door open slightly and then the whole casing and roller comes out in one piece is this the case that this is how you take the roller and casing out in one piece what are the chances are cracking the glass what are the safety requirements I should consider not to crack the glass

In most doors, once you unscrew the housing from the frame it should come out easily enough with a little encouragement. However there are some doors where it is necessary to remove the bottom rail first. In these cases you do have to be careful to avoid breaking the glass. After you remove the screw holding the bottom frame piece in place, you would take a mallet and block of wood and gently tap the rail off. You don't want to use too much force for obvious reasons, just enough to get the rail off.

Keep in mind that I don't know if this is the kind of door you have, I'm just explaining the two most common scenarios you'll encounter for patio glass door rollers.
