You may need different spacers to center the rear wheel in your swingarm, and the front in the forks. The sprocket carrier may have the wrong offset from the center of the wheel and will need to be milled down or your sprocket may need spacers to get the chain line right.
It's probably a drum brake, and that shouldn't present much difficulty to adapt to your bike.
The front brake may pose some challenge, if you want to keep your original front brake and swap it over to the comstar, you may have to drill a few new holes in your brake rotor carrier to adapt it to the comstar hub.
It can be done, but be sure to get all of the measurements on paper first before spending a dime on anything.
Asking if it'll work is a relative question, you'll probably have to do a ton of measuring, have some spacers made, and maybe even find some wheel bearings to allow you to use your original axles. Check the link in my signature line for some documents that may help along the way.
