Wow such an amazing response to something I found! Wat are the 2.25 petrol motor like? Pretty gut less? I might take on the challenge and do it myself! One question is the brake pedal seems to be flat to the floor? Are all 4 brakes gona be seized up and need looking at before I can even drag it out?
the brakes will most likely only be seized if some kid has climbed in it and pressed the pedal and the pedal pivot had gone stiff, what you may have is an awful lot of rust built up in the drums locking the brakes on giving the impression of seized on brakes
more likely the fluid has escaped and someone has pressed a dry system/pedal to the floor and it's stuck on the pivot, the return spring attached to the pedal isn't that strong or shouldn't be, you should be able to see two springs in the drivers footwell attached to the clutch and brake pedals and back up to a bracket in the top of the footwell (both possibly rotted off so only remnants left)
depending on my mind at the time of dragging it out of there i'd possibly end up taking the wheels off and just smashing the drums off if i couldn't get the wheel(s) to turn once jacked up and the box in neutral (make sure the high/low lever isn't in neutral as that locks the front and rear together) on the assumption that if it's refusing to rotate the drum is probably way past it's best (possibly best to remove the props to ensure it's not in 4x4)
but even with seized wheels it could still be winched onto a trailer, DO NOT attempt to suspended tow it (towing on a dolly) without taking off at least one of the props as it may be stuck in 4x4 and with a pair of wheels still rotating it'll try to drive itself forwards off the dolly
looking at that front bumper hanging off i'd drag that forwards by passing a rope right underneath it to the REAR axle so when towing the axle is pushing the rest of the vehicle forwards (this is assuming the rest of the chassis has gone paper thin)
or you could tie a rope under the motor to both axles, each end of the rope to one axle so it gives a loop out under the front of the motor and then attach another rope to that, this means you should get a pretty balanced pull on both axles minimising the risk of things collapsing
DO NOT try to snatch it until you've assessed any rot, tow it out as gently as possible, i've seen chassis that have sat that you could squash with your bare hands and that have just crumbled away when grabbed
this motor looks like it's sat in the damp quite a long time, you could be lucky but i doubt it
a decent 2.25 petrol is quite a nice healthy motor with a fair turn of accelleration and speed considering the general age of them and you're driving a barn on wheels, they're also a very nice quiet engine when running correctly
i chased a mate in a run of the mill 88" with 2.25p through a few lanes back to Warwick whilst in my 200tdi'd 109 and to be honest i struggled to stay with him, ok he knew the roads but even if i had as well i reckon i'd still have struggled
they're great little motors which thoroughly deserve the following they have, i've a mate with a 1962 S2 who has owned it the best part of it's 51 years, it's his only car and has been ever since he bought it as far as i can make out, he's reasonably regularly off to Tallylyn in it as he's a steam enthusiast and supporter/volunteer on the railway there, he may be getting a little doddery but his landrover is still a sprightly old bus
anyway here's another jealous person
best of luck with it
