Offshoreonly.com - Rear engine mount difference

Does anyone know what the difference is between Merc p/n: 8M0103028 and 865330A02? I'm trying to install my motor and want to put new rear mounts in. I keep coming up with two different part numbers for the same thing. One is $20 more than the other, but I can't see any difference in the pic or description. This is for a brand new Merc Bravo 3 transom assembly mating to an older flywheel housing (1997 Gen VI 454). I wanted to update the mounts to the new knurled design versus the double wound washers.

Thanks.
