They usually don't let us take hydraulics into a P&P up here, but they're willing to do the hard work for an additional fee.
I think the motor mount nuts are 19mm and a swivel u-joint with various extensions is very helpful. The tranny is a PITA with those reverse Torx, I'd be very tempted to drop the subframes and take the whole deal. Of course the harness and DME if available as well.
