From the January, 1970 issue of MCS, coverage of the "Fifth MCS/USRA Road Race". I imagine this race took place in September of 1969 or so.
Here is a pic of Mike's car:
I just re-typed the caption text (bold is mine):
"Mike Steube took a second in the main with this unusual chassis. Mike made his drop arm from double rails of piano wire. The front of the drop arm and the front of the bat pans are soldered together instead of being hinged, and some extra brass is added to the front of this to put more weight on the pickup. Power comes from a Champion motor and, naturally, a Steube armature."
I couldn't figure out what this meant. Does it mean the whole front end is all "locked up" like this?:
If so, it may be the first instance of this type of rigid design.
Or do you think the pans still tilt from side to side? He still has the (low CG type) pan stops, which would indicate they do.
I just can't tell from the pic.
