We used to do them by sticking the jib of our engine crane in through the passenger side door (after removing the floor panels of course - always an apprentice job) and dropping the box to the floor. I did see it done once with two very big chaps, one on either side, with strapping under the box front and rear and round their shoulders - very red faces and lots of veins standing out! Having been used to wrestling gearboxes out of Marinas, Escorts, Cortinas, Dolomites, etc, etc. (once changed the clutch on a MK2 Cortina on my own lying on my back in the gutter with two of the car's wheels up on the kerb and the box tailshaft balanced on my knees whilst I guided the bellhousing with my hands - I must have been nuts? Oh no, I forgot, I was just young and invincible!) But the weight of the Land Rover box surprised me.
We've had Pandas for many years and semi seized front calipers are common. The old mark ones with their wedge type calipers seemed particularly prone but even our newest one, Becky (I'm afraid all our cars have names) needed attention when we bought her. Usually I find it's just a good clean up and some anti seize (ceramic Ceratec these days) but it's always worth just pushing the piston back a little to see if it's free moving. Not too difficult to do but if you have the type of caliper like mine, with the pin at the bottom, if it's badly seized (ours was) then don't hit it too hard with a hammer/punch as it's easy to break off the little lug. Here's a picture just for illustration. Of course you would be punching the other end of the pin to remove it.

I'm pretty sure there is another type of caliper which uses two bolts to hold it on (as many do these days) which might be easier to deal with.
somewhere I've got a post on here from maybe a couple of years ago about freeing of Becky's front calipers if you can be bothered trying to find it. If I track it down I'll post here.
PS Hey, I found it already - the bit about Becky's brakes - Type into the search bar "Becky's brakes - a few surprises" and it should come up.
