Turning back the clock

Can't tell if the roll bar is tied to the frame connectors, looks like it isn't? Aren't the side bars supposed to be shoulder height or some such thing or maybe that's a later roll cage development? Must be a P.I.T.A. to get in the car with them like that though. Gotta love 2" round tubing for the frame connectors.

Looks so flimsy with it all open.
