Which Hull Anode for 37' Tiara

[Lured Away]

Trying to order zincs from Boatzincs.com and checking if anyone can tell me which is the correct hull anode for a 1998 37' Tiara?

Looks like B-12 (5" stud centers) or B-15 (5-1/8" stud centers). Only difference is 1/8" on the stud centers but the B-15 is also about $50 more each.

Thought I had measured 5-1/8" but zinc store thinks is 5".

Thanks

Ryan

I'm almost possitive I used B12's on my 38
