Thanks, Doug. I think the Landrover kit is probably for four cylinders - and there are two cylinders per brake drum. (They are not 'double headed' cylinders so only have one seal and one dust cap per cylinder). It's interesting they provide gaskets with that kit, but not for other similar looking kits. I'm going to the Beaulieu Autojumble this weekend so will have a rummage around and see if I can find out more.
