I hate lowering motors in with those horrible chinese jacks. You have to be sooo carefull when turning the release screw to let it down. Two hands on the handle the whole time.
If you have one of the cheapo China engine cranes, like most people do, you can stick a proper handle on that release screw.
Or stick a bush in the end of the arm so it locates positively, and weld a radial arm onto the arm. Both of these things will give you much nicer progression/control of the lowering process.
I hate shit tools that fit together poorly. But everything can be fixed with a lathe and a welder.
Car is looking good.
That's a familiar face!
