Giving this a try. This is what I know so far. The boot will fit as OP suggested, there are some caveats to that. I'll try to point them out below. I'm replacing a torn inner boot that lasted about 1 1/2 years since I rebuilt them.
Here is what comes in the kit:
A comparison of the snap ring used inside. The original I have from the OEM Land Cruiser version is thicker (it is on the right in the picture below). I used it again.
A comparison of the large ring that holds the tulip in (new one is on the left). They looked exactly the same. I used the new one from the new kit.
There are differences inside the boots. The original Land Cruiser version matches up perfect to the cv axle, obviously, so there is a tight seal. Check these comparisons of the inside:

Final thoughts:
The boot fits pretty good on the larger side, there is an outer ridge that "snaps" in place and it feels like a solid fit. The smaller diameter side is loose on installation. You can move it back and forth before clamping and there isn't an exact ridge or set of ridges that matches up. I'm not sure the included clamps would work, they might but I kept the rounded edge McMaster Carr clamps. I actually used 2 new ones for the test.
My initial impressions are that you can crank down these McMaster Carr clamps to make up for any looseness in the small side, since the boots are much harder and not the soft rubber that the Land Cruiser version was.
I've only got a few miles on them but I'll update back here with any major news good or bad.
