I need a repair kit for my circulation pump on my volvo penta, where do I find it?

If you have the old circ pump 860358 you need to purchase the old repair kit 876270.   This repair
kit is NLA but I can still get you one for around $425.

If you have the new circ. pump (or newer rather) 3812236 (or the very new one 23401753) then you
would have to get the newer repair kit  3812230.

In both case to get the ceramic like seal you have to purchase the entire repair kit.
