David, you must be incredibly slim if you are going to crawl under a Morgan with no form of lifting!!!
I have been able to do part of my rear springs from above, but as the car still needs to be lifted to do the rest, might as well just get it in the air.
I do miss the garage at my old place - and its full length/depth inspection pit!
Cheers,
Even so, I would find it difficult slipping underneath
