79 kz650d with 03 gsxr750 fork swap help please

Hi-- i joined this forum, got all revved up, and bought a 1979 kz650d frame, and an 03 gsxr750 front end. I have read all the gsxr/kz650 fork swap threads that i can find and i see two possibilities 1: I can use the triple tree stem off the gsxr in its entirety, just ordering new bearings from a place called all balls---or 2: I have to get a tree off a kz650, press out the stem, and press it into the gsxr tree. which one of these is accurate? I read someone was having problems getthing the kz stem correctly in the gsxr tree. ideally obviously id leave the gsxr front as is. I have to send out for any machining. this bike will have a custom jmc swingarm, both 00-03 gsxr wheels/brakes/clip-ons...thanks!!!

According to All Balls, one of the following bearing sets ought to work. No idea why there are five.

Click on the "Find Fork Conversion Bearings" on teh left side and it will open another page that works.

I have no idea whether the stem is going to be the right length to work though.

thank you!! yes those charts are helpful--Im going to search around about the stem length issue--

steell do you know if the stem length of different year and model kz650's are the same??

I'm not 100% certain, but I believe all 650s up through at least 1980 have the same stem length.
