When I bought my mid 80`s +8 one of the first set of spares I collected for it was a full set of hydraulic seals. I have no idea if the MC on your Mog might be the same dual circuit type as mine but the green Lucas box identifies the kit as SP1967 also there is the name Girling on the label followed by 18/03 810 and below that 744793... Hope this helps and does not muddy the water..
