Can someone please post the dimensions for the T-Slot for the Tesla Roof Rack? I am wondering if my BMW Bike Racks, which also used a T-Slot install would fit the Tesla rack. The dimensions for the BMW T-Slot was 1" wide by 1/2" height and a little more than 1/2" gap on top to hold attachments. The head of the screws that slide into the t-slop was flat and was little less the 1" by little more than 1".
