e34/e36 ? 323i euro flywheel?

[Herb]

If the 323i 228mm flywheel is the same size as the e34(dohc) flywheel, what would stop me from using it. This is an honest question, my e30 w/ s52 has the 323i euro flywheel/e30 m3 clutch assem./ and 260 getrag. The big difference/question is will it fit the e36/e34 getrag trans. Why or why not.

Thanks All,
Herb
