rear wheel for FLSTC

[2manycats]

Hi all,
I have a question about rear wheels. I have a 2010 heritage, and I want to get an extra rear wheel to try and seal the spokes so i can go tubeless. I did it on the front and it worked ok so far (knock on wood). On ebay they have a rear spoked wheel from a 2004 Sportster, with a 3/4 axle. Is the wheel the same, and I just have to put in 23mm bearings, and I'm good to go, or are there other things I'm not seeing? Thanks.

I can't answer your question about the wheels being the same but am very curious about the method used to seal the spokes?? Might be something others want to try if it is a proven technique that works well.
