I've searched high & low without avail and I'm hoping someone can assist me with identifying the various sizes (I.D.) of vacuum hoses that I'll need to replace on my stock '72 240z. I'm going for functionality, not points so I'm fine going with auto-parts store grade vacuum hosing. Any suggestions would be greatly appreciated!

A caliper, pen, paper and 10 minutes should do it.

Pen??? whats a pen???:classic:

Isn't that where the pigs live?
