Been awhile. Not really a fun job...

If I recall correctly I found a series of higher items to slide/drag the pumpkin on to. First I had the pumpkin on a piece of plywood and slid it under the car, and then I slid/lifted/dragged the pumpkin up a few inches higher on to a couple pieces of lumber, then it was something else a little higher, and so on. Then at some point it was high enough off the ground where I had enough leverage and strength to pick it up and install it.

Was a bit like a game of Jenga, with a big heavy object on top...kind of tilt the pumpkin enough to put a piece under one side, tilt it the other way and put another piece under it, and so on.

scrap lumber is your friend.

Another approach is put it on a milk crate or similar, and then weasel pieces of scrap lumber under the crate.

A trans jack would be nice to have....
