We've had two Mini's and the easy way to access the engine/trans is to drop the subframe with engine, lift the body higher, and roll the subframe unit out from under the car then go at it from there. Much easier than trying to weasel the engine/trans out through the top. Joe
I had a 1963 Mini Countryman woody wagon, right-hand drive with the 850cc - 36hp motor, "magic wand" shifter and non-synchro first gear. Upgraded it with some bolt on Cooper S parts to a whopping 50hp (est). Still wouldn't get out of its own way, so I sold it on. Fun to drive on the flat or downhill.
