Water heater anode length-3 gallon H20 heater

[B_and_D]

Has anyone replaced a water heater anode for the older, 3 gallon Suburban water heater? I need to know how long it is. I'd rather have one on hand before I pull the old one out (who knows what it looks like by now).

I emailed Ed at the factory but he could not answer my question.

I've been dreading doing this but I think it's way overdue.
