Rod tip replacement help

[C-Bass2mouth]

I'm needing to replace the tips on 2 of my rods. Abu Garcia Veritas 6'6" med spinning, and a Abu Garcia Veritas 7'6" MH casting. I know the ring (what your line runs through) size is a 6 for both rods, but I can't find what tube (the piece that slides over your existing blank) size is. I called Abu's service department and spoke with a lady who was zero help. She said that there are no specs for them I could look at either. Kinda hard to believe being they f'n mass produce them. I could take my own measurements but they're measured by 64ths of an inch so mine probably wouldn't be too accurate. Was wondering if anyone that maybe builds rods could help a brotha out on a tube size.
