How do I determine which CV joints I have?

I have a 94 S110P. How do I figure out which CV Joints, either 71LAC, or 75LAC? And, can I determine which ones I have so I can order new boots, and rebuild kits, before I take the ruck down to do the repair? I’d rather not rip it apart, and then wait a few weeks for new parts to get here?

 

https://partsfan.com/ put your serial in and look at the fiche also i order a lot of parts from https://en.impex-jp.com/

 

Thanks, the parts sheet shows a 75 next tot he boot kit, and plugging the Japanese into Google Translate,
