A lot of things aren't connected yet and the steering column isn't there.
Thinking about it, I think I know how to do it. I pre-bend like a big up-side-down U that goes across behind the engine. Then I do the bits on the ends in place. Lying on my back. With my nose rubbing the trans cross member. Poking myself in the eye with brake line.
Wee. Sounds like fun.
