Thanks for your advice. I did think that if it weren't for the engine mount being in the way, the job would be a bit easier.
I have a trolley jack, so I might make up a brace that I can bolt onto that end of the engine and then jack it up a bit or enough to take the weight of the engine and see how I go for space.
Once again, thanks very much for your input.
