It seems like the assymetric roll cage isn't legal (Blue Book) is pretty vague, as it doesn't protect the passenger seat (there is no passenger seat!).

Shame!

And the fuel tank plonked in place.

The roll cage is coming on well too!

The gear linkage and flatshifter are now finished.

Front wishbones are done! It's starting to look like a car now! 

The gear linkage / quadrant - just waiting for the flat shift sensor to turn up!
