Yes, call a prop shop (as mentioned above), but before that, talk to Vans to see if they think it's actually too much diameter for your airframe, & even call Hartzell for their thoughts of cutting down that blade.
From referring to

I understand the
7666A blade is the 76" version
7666A-2 the 72" version
7666A-4 the 74" version
If the solution is to sell your prop, the model currently sold by Vans is supposedly slightly lighter, some claim a bit quieter, & a bit faster than the older 7666 profile.
