Get a good alum. floor jack (light and manuverable) place a board that will cover the trans. pan and a buddy to steady it and there you go. A turbo 350 or 400 is no problem but your car has to be up enough so when you let it down it will come out from under car. Same with rear end. Then go fly something such as your minnow and when you get back start again. IF you crash it this will take it off your mind lol.
Same here though built this and scared to put it on the road.
