I’m undecided ... I have never done a comparable task. Some people here in the forum did it without any previous experience, too, and were successful. I’m currently looking what tools I would need: an engine stand - not too expensive. An engine crane can perhaps be borrowed. Regarding the nuts and bolts that are rusted and, thus, hard or not easily to open, I would buy an induction heater instead of using a flame. For the labour costs in the shop a lot of tools could be bought :-)
