My hood vent is impossible to open or close while seated. I rigged up a handle that hangs down so now I can manage to open and close it while driving without opening the door and reaching up there on my knees. Did MGBs originally have a handle of some sort that my ‘70 was missing?

Jeff,

I'm not sure if this will make you feel any better, but my '70 is exactly the same as yours.
I have to get on my knees to be able to see and grasp the handle to operate the vent.
If I tried to operate it from the driver's seat, I would need to have 2 wrists on one arm in order to get my hand at the proper angle.confused smiley

Yes - most often the question here is "what's this white knob do?" and the answer is "opens the fresh air vent".

Well if you think you need two wrists spare a thought for us with the steering wheel on the correct side tongue sticking out smiley

Then it was rinky dink from the factory. Not as greivous as the heater control valve I suppose.

Use the one from a RB car that has the longer arm. Check the buy, sell, trade forum if you want the one that will work for you.

The knob on the 70 is black....

Try lubricating the hinges and the spring loaded roller. Mine works ok.

Thye spring loaded roller needs to be well lubricated and not binding anywhere. Then you simply pull backwards on the lever which is on the left side of the vent. Should be a doddle for LHD cars.

1968 MGB Purchased already dis-assembled but which is largely back together so I'm a lot less ignorant.
