Convertible/Hlwyd Question

    What is this hole for? Picture shows a threaded hole halfway between the two bolts that hold on the vent wing onto the door of a Convertible or HLWYD. My guess is that this is an adjustment "knob" that goes behind the vent wing, which would allow either the top or bottom bolt to be tightened more or less than it's corresponding fastener to allow one to change the vertical angle of the vent wing. Sound correct? If this is the case, what was originally here, an all-thread type of bolt or an actual bolt (with a head on it)?

    Seeing as how this scenario is only on a Cv/Hlwyd, and is the same vent window, I don't see any other purpose for it. I ask because I just finished repairing holes, finding hardware, repairing broken brackets for the vent wings, installing new gear mechanisms, etc. It's very easy to make the vent wings fit "funkily", or not very well at all. Fortunately, there is a lot of adjustments, and this would just be one more that would make sense. I had thought of just shimming one of the bolts with needed washers, to change the angle, but curiosity has gotten the better of me. My OCD is acting up again . . .

    Russell,

    Take this as a compliment... because of your OCD that car is going to turn out flawless.

    Early 48 vent window frames used the upper two bolt holes on the door to bolt in. They then figured they were not strong enough so modified the frame to bolt to the upper and lower bolt hole on the door (leaving the middle hole there through 1954) Actually had a early set and found also there was not enough support there.

    Thank you, Russ. I knew there was a logical answer behind it.
