I'm not aware of where to get one since I haven't had the need to have one changed yet. But, I have seen them on an 850 Turbo Sedan before. I was at my local dealership and when talking to a mechanic working on a dark green 95' 850 Turbo Sedan, I noticed they non-machine made seam on the CV boot, on the passenger side that was not on the driver side, and asked the mechanic if it was indeed a two piece, and the mechanic noticed that too and said yes. And I know this and these mechnics at this dealership, and I know they wouldn't lie to me about things like this. The owner wasn't around; he just left the car for service and probably went off to work. I made sure to remember the way it looked for future reference.

I then later saw a friend of a friend install one on an Acura Vigor/Legend (can't remember) and it was the same seam, so I'm absolutely sure the one on the Volvo was a two piece.

Actually, the hub removal only takes about half an hour (not including prep for taking the stuff off), and is good practice at doing brake work, as well as getting a person to actually inspect stuff. Anyways, I assume the amount of time you have to wait for the epoxy/adhesive to dry/cure will take a couple of hours to be safe. And there is no way a two piece boot will last as long as a one piece, and I'm sure it takes practice to make a good seam on a two piece.

I can ask a friend that confirmed the existence of two piece CV joingt boots if he knows where to get them. I'll try my best to remember to ask him the next time I see him.
